Constipated

My 2 week old hasn’t pooped since Sunday - so we’re on day 3 now. I breastfeed and supplement with formula.. the pediatrician said to give the baby a warm bath and massage the tummy and bicycle her legs, then follow with a rectal temp to see if it stimulates her bowel movement..... none of it worked!

Anyone have any tips?

We have her 2 week apt tomorrow where we’ll address with the Dr 😩
