I mostly EBF for 5 total months, with 50/50 pumping & nursing for 3 total months, then mostly exclusively pumping with about 1-1.5 bottles of formula a day, months 8-11. At 11 months I basically quit exclusively pumping and only comfort nurse - I don't have a lot of milk left.

Months 8-11 he had 5 feedings: 5oz, 5oz, 5oz, 2oz, and 6oz. The 5oz ones were breastmilk, and the 2 & 6oz ones were formula. Total of about 23 daily oz. He never had any real problem with formula.

Now I can barely get 16oz of just formula into him during the day (I'd do more, if I could). Xmas screwed up sleep so we're back to about 2-3oz at night, as well. Every time the bottle is offered, he'll drink about an oz, then push it away. ALL DAY LONG. A sippy kind of helps but not enough. we've tried different temps, times, toys while drinking, etc.

Do you think he is rejecting the formula taste/amount? Is he weaning himself since it is all formula now? Is he ditching his own bottles and preferring sippies? Did any of you go through something similar at this age?
