My LO gracefully drinks her bottle during the day, sucks effectively and sits still while drinking. At night on the other hand, she moves about during the entire feed as if she’s full of wind or not hungry trying to the bottle out of her mouth and also doesn’t suck properly (if I don’t pay attention she will just play with the teat in her mouth and not swallow anything). I’m not sure what’s going on and why she isn’t drinking the bottle properly at night like she does during the day. LO is four weeks old yesterday.
