Bunk Beds

when he starts climbing out of the crib, it’s a good time to move a bed into the room. lower the crib rails & let him decide where he will sleep. with two weeks, he’ll choose & bed time will become just a bit more difficult.

It is hard to tell not knowing the maturity of your son. However, you’re not even pregnant yet !!!!
Let him go into a new bed when you think he is ready. I would always take Baby #1 out of the crib 3 or 4 mo. before Baby #2 arrives. As for being in a top bunk, that is another story. Some kids seem to fall out of their beds a lot and some never do. I would certainly have sturdy side rails on it.
You know that everyone does not become pregnant at the exact time that they plan to do so, even if it happened easily the 1st time, so I wish good luck to you next June.

Your son should be fine moving into a big boy bed now. Typically you want to as soon as they start trying to climb out. Seeing how your child is almost two, he should be able to handle it. I would start now if I were you, get him used to it before you get pregnant, that way he will be able to let his younger sibling have his old crib with no issues. I would get him a toddler bed first though. Since he is used to the crib, he might fall off a regular bed. A toddler bed has sides on it so he wont roll off. When his sibling needs the toddler bed, then I would get him the bunk bed. Only I would get the kind that can separate into two different beds so in case you move again and get a bigger place so they don’t necessarily have to share a room. Also, this way your child can have his own bigger bed, and you can put the other half in storage until the younger child can use it.

when to switch from crib to bed

"There’s no set time when you have to replace your child’s crib with a regular or toddler bed, although most children make the switch sometime between ages 1 1/2 and 3 1/2. It’s best to wait until your child is closer to 3, since many little ones just aren’t ready to make the transition. Of course, you’ll need to move your toddler to a bed when he’s simply too big or too active to sleep in a crib anymore. And once he’s potty-trained, he’ll need to be able to get out of bed to use the toilet.

Many parents make the switch because they’re worried that their active toddler might climb or jump out of his crib — and this is a real safety concern. But it’s best not to react to climbing out of the crib or any other sudden sleep problem with a sense of alarm. Don’t rush right out and buy a new bed the day your toddler first climbs out of the crib. He may not be ready to move to a bed, and it may not be safe for him to be up and about during the night when everyone else is asleep.

Buy yourself some time by lowering the crib mattress as far as possible, so the side rails are higher and more difficult to climb over. And always remove padded bumpers as soon as your toddler starts to climb. In addition, consider installing a crib tent, which is mesh and attaches to the crib rails with Velcro, to keep your little one safe and snug in his crib.

Another reason parents make the switch to a bed is the impending arrival of another baby. If this is your situation, make the switch at least six to eight weeks before you’re due. You want your toddler well settled in his new bed before he sees the baby taking over "his" crib. Depending on your toddler’s age, you could also consider delaying the switch until the new baby is 3 or 4 months old. Your newborn will probably spend those months sleeping in a bassinet anyway, and your toddler will have time to adjust to the new baby, making the transition to a bed easier when it does happen.

Be sure to base the timing of the switch on your child’s readiness rather than on the need to free up the crib, however. Many parents find out too late that it would have been easier to borrow or buy another crib rather than move their older child to a bed before he was ready.

Some children adjust readily to this change, while others have a hard time with it. Every child is different. It’s not unusual, though, for firstborn children to resist the transition. He may be very attached to his crib and all of his associations with it. The move to sleeping in a bed is just one of many changes at this stage in a toddler’s life — it may coincide with toilet-training, starting preschool and other pressures to "grow up." If a new baby’s on the way, your child may feel possessive of his baby things, including his crib. Later-born children often have an easier time making the switch to a bed because they want to be just like their older brother or sister. They’re eager to move from the crib, which is "for babies," into a "big-kid bed." However some toddlers, whether first- or later-born, are just plain ready and relish this change in their status.

To ease the transition, put your toddler’s new bed in the same place his crib used to be. If you’re using a twin bed, you may not want to make an immediate switch to grown-up sheets and blankets that are tucked in. Your child may find it soothing to continue to sleep with his old crib blanket, even if it’s too small. Don’t forget to put up a guardrail to prevent your newly liberated toddler from falling out of bed.

Get your toddler excited about having a "big-kid bed" by taking him with you to pick it out, if you’re buying it new, or by emphasizing its previous owner if that person is someone your child knows. For example: "This was Cousin Petey’s bed and now it’s yours! You’re almost as big as him now!" Let your toddler shop with you for new sheets featuring his favorite characters, and encourage him to show his "big-kid bed" to visiting friends and family.

Another tactic, although it requires a little more work, is to throw a "big-kid bed" party. Choose a date to unveil the new bed, and talk up the event a week in advance. On the big day, have a party and invite friends and grandparents.

Another strategy is the use of specific "toddler beds". They use a crib mattress, but look more like a regular bed. Many come with built-in guardrails, and some are made in very appealing themes and shapes, such as cars, trains and pink four-poster beds.

If you find that you’ve made the switch too soon and your toddler is upset, don’t give up right away. Encourage your child to try out the bed. If he’s still distraught after a few days, bring the crib back.

Some toddlers simply aren’t ready for a bed. It takes a certain amount of cognitive development for your child to understand that a bed has imaginary boundaries that he must stay within. If you find that your great sleeper all of a sudden takes a long time to fall as
