DS always, always, ALWAYS does poo when he is put to bed for both day naps & more often than not at night too.
He mucks around having a grand old time & won't settle until his nappy has been changed. After this he'll just go to sleep on his own.
Nappy gets changed by his night light, we don't speak much or loudly, change him in his cot etc. It's not like we make a big fuss or do anything exciting!
It doesn't bother me, I'm just curious if anyone elses toddlers do the same thing?
