Regressing with food?

Same thing happened to me i was worried about it too. Teething can start as early as 3 months, that pain and itching can make babies not want to move their mouth to eat from the pain until it passes. Sometimes their hunger decreases if they went through a growth spurt and when they hit another their appetite may increase again. As long as baby has regular wet diapers, no constipation with normal texture when baby does give dirty diaper and no signs of weight loss. If you notice feeds are taking longer than 30m you should definitely up your nipple flow if you haven’t yet, feel on baby’s side to prevent choking at first until they get used to it. Good luck!

This happened with my little one! She would usually take anywhere from 100-120 mL, but then she started only taking ~60 mL, closer to 80/90 if she’s hungry. It was just a developmental leap/growth spurt. It lasted for about 3-5 days, maybe even closer to a week. She had jumped from 50th percentile in height all the way up to 90th percentile in height. All that growth was super uncomfortable for her! But once it passed, she started eating normally again. She was also super fussy during that time!

I was also nervous that she started having bottle aversion so I tried different glass bottles (Philip avent/dr browns/etc.). It wasn’t the bottle, haha. It was just the growth spurt. After it passed, she preferred her original bottle (Lansinoh). I had a friend where the moment she changed bottles, her little one started eating normally again! Every baby is different, as long as she’s hydrated (enough poos and pees), you could always wait it out a couple of days or try different bottles or change the nipple size! My baby was getting frustrated with the XS nipple and it had been awhile since we sized up, so we changed to S and she’s much happier! We’re about to change it to M now that she’s approaching 4 months.
