Dear A.,
Some little ones need a bottle longer for comfort.
I am the mother of five grown children, but still keep
in contact with homeschool moms, for mutual support,
so that is why I signed for this list. I am the grandmother
of four, including 9 month twin boys.
I know that pediatricians have lots of reasons to take a toddler off of the bottle, but you are the mom, and if you see that the bottle gives your little one comfort, then let her have it, even until she is two years old.
Some time after their second birthday, our toddlers "kissed their bottles" and put them in the trash. That worked with some, but if you do that and she cries non-stop for a day or more for her bottle, then she really wasn't ready. Give it back to her and ask her to tell you when she is ready.
I know this is not "modern" advice. But you would be surprised, I know moms with big families and they have learned to wean, potty train, etc., when their child is ready. And EVERY child is ready at a different time.
I hope this helps.
Grandma J..
