Just wanted to echo the notion that your child does not actually need MILK to be healthy, just the essential nutrients in it which are found in other dietary items.
Also, I do agree that some babies do wean themselves quite early, despite our best intentions. Breastfeeding is wonderful, but re-lactating and forcing a kid to BF in many cases isn't possible, desireable, or IMO, worth the angst. The suggestion of this "remedy" to the OP's simple dietary question makes me want to defend her, and I'll probably go all tangential on here....
My son never really liked nursing, in fact went on a 5 week breast strike at 4mos. old, I fought that by pumping like crazy b/c he was so young, he finally went back to only nursing at night.
Now at 10 mos, he's adamantly done with it. Yes, I wanted to keep going, and tried my best, but he's also got his own mind about it. He still eats healthy food and is thriving, so we have chosen not to fight this battle.
(Oh, and he has a metabolic disorder. We didn't have the luxury of allowing him to wait till he was really hungry to enforce breastfeeding, so we use formula when needed. Formula actually saved his life, but that's for a different thread.)
Isn't a healthy, happy, thriving child, (no matter what they drank in infancy) a more tangible and valuable end result of being a good parent?
I think we all just want our kids to grow up with an healthy long-term relationship with food, so choose your battles carefully.
