My original post was moved to Breastfeeding - overcoming difficulties (not sure why!), but I wanted to give everyone an update since you were all so helpful!
Kayla took a bottle at daycare Wed, Thur and Friday of last week! Her pattern is to take 1-2 oz at a time until she gets really hungry and then sucks 6-8 at once. Holding out on feeding her until she was hungry is what did the trick!
Also - she took a bottle from my husband yesterday and today WITH me in the house! Yeah!
