My daughter is 18 days old and for the last few bottles she's suddenly decided to guzzle them down without pausing? Then she's getting panicky because she's obviously taking on too much milk and she starts gasping and shaking her head to get the bottle away. She's not done this before, she normally drinks them okay apart from a bit of leakage around her mouth. She'll usually pause as and when she needs to. I don't know what's changed or what (if anything) I can do about it? I try and keep taking the bottle from her but she can literally only manage a few sucks each time before she's panicking. It's making it such hard work to feed her and then if the bottle isn't in her mouth she falls asleep so I keep having to try rouse her to take more 🙈
