Fomula fed newborn babies

Hi mommies
I am changing to full formula milk for my 3 weeks old baby.. she poop yesterday.. but today seems like she is straining, then pass some wind.. not sure if this is constipation? She is drinking Nature One premium now...

I guess it is totally fine for the babies to react a little bit when changing formula or switching from bf to ff. I have been giving my baby Enfamil A.R after I switched to BF. It is working well for now.
