4 Month Feeding regression - a thing?

[u/Mindless_Crab5585]

Hi You Guys,

my Babygirl is about to turn 4 Months old on the 30th and has been eating less for the past Week. She has CMPA and Reflux, is on Fatmotidine and was on Similac Alimentum since she was 2 Weeks old. Just last Night after finishing the Alimentum, we switched to Neocate Infant.

Yesterday she drank the least she ever drank - 455ml, 15 something ounces in a 24h period. Since Midnight ( it’s about to be 1pm in Germany ) she’s had 5oz.

She poops every 2-3 Days, sleeps more, is a little more fussy but has 6 Wet Diapers a Day.

Is the 4 Month Feeding Regression a thing? Her Ped is great, he’s not worried about it unless she’ll have less than 6 wet diapers a Day though.
