I still demand feed my 17 month old because...well...I really couldn't be stuffed fighting with him about it

He is pretty good though during the day, he has an early morning, lunch time and evening feed but he will occasionally want to snack during the day which is fine. He still feeds twice over night though and THAT is what is really getting to me lately

It's really up to you and your bub, just do whatever you're both happy with.
