Help on feeding - baby suddenly refusing to drink

Hi! My LO is easily fulfilled by food (not very greedy one hahahah) and goes through phases like that once in a while lol will drop for a few days or 1-2 weeks then suddenly return or increase drastically. As long as gaining weight shouldn't be a big problem - they're just like adults sometimes got more of an appetite and sometimes don't. My baby is currently sick for the last 2 weeks w cough, dropped from 900 to 600+ as well. But if you feel that something is wrong then do consult PD!

My LO also like that recently. But its cos of teething and sleep regression. I just make sure she finishes her meal :)
