So just a little background info, I work a few days a week and my daughter used to be supplemented a bottle or two of formula if I didn’t pump enough milk beforehand. All of sudden this week she absolutely refuses to take a bottle if it has formula, if it has my milk she is fine.

What do you ladies think could be happening? My MIL who takes care of her while I’m working has tried different formulas and she won’t take any.

Any insight is appreciated!
