Still demand feeding my nearly 22 month old He feeds quite a bit during they day when I'm around - sometimes hardly at all, but as a rule, he'll feed at least 4 or 5 times a day. I do offer it when my supply is all over the place and I need to offload, otherwise I let him ask...and he does!
Not planning on scheduling him. When he's sick he'll feed more (like ATM), and that's cool, cos at least he can have something other than water when he's got a tummy bug!
