My 2-3 months old keep refusing to drink & want multiple breaks in between feeding. Help!

Ah, don't worry too much, a few of us went through exactly this around the same age! Around 2-3 months there's something some mums call a "feeding crisis" where babies get fussy and distracted, and one thing that really helped a friend of mine was feeding in a dark, quiet room because her baby was overstimulated and would only drink calmly when her surroundings were settled. It's also worth checking small things like whether the nipple flow is too fast or too slow, or trying more frequent burping mid-feed since the breaks could just be baby's way of managing discomfort. Someone in my mum group also mentioned that reflux or even an ear infection can sometimes cause babies to pull away during feeds, so if this keeps up or baby seems uncomfortable and isn't gaining weight well, do bring it up with your PD just to rule those things out!
