Fussy baby when feeding


Daughter is 12 weeks on Saturday. Formula fed. She used to suffer with trapped wind issues but has got so much better at burping recently. However in the last week she has started to be fussy at feeds. Will take the first 100ml or so no problem but when she’s next offered the bottle starts crying. It’s like she doesn’t know what she wants and we just have to keep alternating between offering dummy and bottle until she’s eventually had enough milk and settles for a nap. Anyone experienced similar / has any tips?
