3-week-old hasn't pooped since last night and strains until she turns red

May have to change the milk. My son was on Similac neosure and he kept having the same problem so I put him on Similac total comfort which is like gentle ease and the problem is resolved now

Im breastfeeding an supplement with formula we switched it to gentlease but it didn't work.. :/

try I little olive oil gave her just a little & rub her tummy with it to that help my baby around that time

Gripe water or put a little Karo in one of her bottles

gripe water, or my 3 year olds pediatrician when she was a newborn told me to give her 2oz of watered down apple juice a day (my daughter would never poop) the natural sugars in the juice helped break down her stool so it could pass. but I would call and check with your doctor before doing that. apple juice is a LOT gentler on the stomach than olive oil or Karo syrup

thank you! I'm gonna try tomorrow by morning if she doesn't poop. I hate seeing her so cranky

My LO dos the same thing around that time. I didn't do anything different he eventually had a bowel Movement on his own. His pediatrician that babies can go a few days without a bowel movement 😕

give her water that will help

did that its not working :/
