Mummy balloon, daddy balloon and baby balloon had slept in the family bed since baby balloons birth. Baby balloon had now grown to such a size that sleeping in the same bed as mummy balloon and daddy balloon was problematic, so:- Mummy balloon said to Baby balloon. "Tonight, baby balloon you are going to sleep in your own bed"
That night baby balloon was put to bed in his own bed but woke at 3am and proceeded to mummy and daddy balloons room. He realised he was too big to squeeze into the bed between mummy balloon and daddy balloon so he let a little air out of daddy balloon...still without success he let a little air out of mummy balloon.....still not enough room to squeeze between his mum and dad so he decided to let a little air out of himself.

In the morning they woke up and mummy balloon in a somewhat distressed tone said...."Oh baby balloon, you were supposed to sleep all night in your own bed and not come into our room.....do you realise you have let your Dad down, you have let me down and you have let yourself down!"

Best wishes, Mike.
