7 weeks old getting fussy on bottle

If he gets fussy now that you give bottle fed then do give unless it is not enough for him. Baby milk pattern change. For me both my daughters ill bottle fed when it is not enough and when I am starting work/they are going to CC. But ill highly advise soon as baby turn 2 to 3 months old, try to FM and interval with BM so baby will get use to it.

Is your LO able to go through a whole 2-3 hours without the FM topup (just BM only)? If yes, then likely your supply has caught up to LO’s needs :) if not, continue to supplement with FM, most likely it is colic or need to burp first before the bottle
