what can I give or do to help my 3 week old baby poop?

call the doctor

that's really young

couple of questions... is baby straining to poop? is baby breastfed?

baby is straining to poop and not breastfeed

ok then yes call the dr.... I wondered about a growth spurt ( my daughter will go a couple days without pooping during growth spurt)

Ok I'm going to call I have tried a warm bath and nothing works it just calms her down

@mommie818, my doctor told me an ounce of either pedialyte or baby juice. Ask your doctor though. Different strokes for different folks
