I think a decline in eating is pretty normal at this age. I wouldn't worry too much! Sounds like your Dr. is micor-managing his weight! I would try more 'finger-foods' that your son can feed himself. My kids were all pretty much done with "baby food" by this age. Or, if he still likes the baby food, give him his own spoon that he can try to feed himself with, while you're getting bites in as well, can be messy and tricky, but it might work:) There are also utensils called 'lil dippers' I think, where the end is just flat, instead of like a spoon, those are fun for toddlers too. Just keep experimenting, you'll both be fine!
