What silly advice from your MCHN! There is no "right" feed to drop last - in fact usually our kids choose it for us anyway and they are all different. DS1 dropped his night feed last, DS2 dropped his morning feed last. That was just what they did. Whatever works for you and your DS is the right thing to do.

It is fine to keep one feed going for as long as you like (and your DS!). DS2 had one feed a day for months before he totally weaned!

Keep up the great work!
