Nicole,

How old is he? does he understand that sleep time and stay in bed? maybe he is too young for toddler bed?

Is he sleeping during the day? if he is and wont sleep at night, maybe time to drop the day sleep???

If you want to drop the bottles in bed, just give him a drink of milk before bed and brushing teeth?

Does he have a favorite toy to have in his bed? that helped heaps with my 2 girls.

Hope I have helped even just a tiny bit. I know its really hard at this stage, maybe if he doesnt understand in a week, I would put the bigger railing back up and try bit later.
He is 2.

He does have a nap through the day. I tried cutting it out the other day, but made the battle even harder when it came to bed time.
His favourite toy is in his bed.

I just don't know what to do. he was crying/tantrum last night for just under half hr. I get ridiculed for him not being in a normal bed, but its just a mish, then having him on the bottle still i cop it for too!
