Toddler Getting Too Big for Crib but Not Ready for Toddler Bed!

[Guest guest]

This question is about my autistic son but it's a unisex question so

I'm hoping that you all can help me because I'm absolutely clueless

as to where to turn.

I'm not sure what to do here. My son is 40 pounds, 44 inches tall

(going to be 3 in Aug) and we have him in a crib with a zip-top-tent

so he can't climb out of it. In the next six months or so, he's

going to be too long to sleep in the crib but he's not mentally ready

to be alone in his room with a toddler bed....and he's not the type

of kid to lay down and listen to a story and then drift off. Right

now when we put him in his crib, he jumps around, laughs and carries

on until he's tired and eventually falls asleep - sometimes it takes

an hour for him to " bounce it out. " It doesn't matter if we wait

until he's exhausted, he still needs that time to wear himself out.

It think it's a sensory thing that he needs to do for himself.

I went online and saw a couple of hospital type " cribs " but they are

over five thousand dollars! I found adult sized (twin or full) cribs

for twelve hundred but the sides aren't high enough to contain him.

We need something that is longer than a standard crib but tall enough

that he can't climb out of it. My son is a climber, non-verbal and

is basically he's like a 6 month old in regards to his

comprehension/listening skills. He still puts everything into his

mouth so there's also a choking hazard if left alone. I can't leave

him alone in any room and I really don't want to start bringing him

into the bed with my husband and I. He's slept in his own room from

day one and I'd like that habit to continue.

Does anyone have any ideas for a bed or have any of you run into the

same problem with your girls? I really need help with this one

because I don't know what to do or where to turn.

As Always, Thanks So Much For All Your Help!
