Hey, I was just wondering if anyone has experienced this and advise me on what I should do. My daughter is 9 months next week, and the past few days she's been refusing her bottle. We switched her from breast to formula back at 2 months because she felt bottles we're easier. And since then she's been guzzling formula down at every meal time, except the past few days. I've narrowed it down to two options: 1. she's been teething recently, and has 2 teeth, but could be getting another one soon (feeding with the first teeth was spread out, but not to this degree). 2. when we ran out of formula this weekend and I ran to the grocery store to get more, they were out of her usual type of formula. So I bought a different type of formula in the same brand. I'm leaning towards option 2, but she's not even halfway through the new tub. Should I just go ahead and try to get her usual formula, or will this pushing the bottle away phase off?
