Ay normal lang yan, mama! At one week old, ang poop ng babies ay usually yellowish or greenish pa, especially kung breastfed, at talaga namang may amoy, hindi siya marurunong amag ng mga bulaklak, hehe. A few of us moms were worried din at nag-panic, pero doc assured us it's part of their system adjusting to feeding, kaya don't worry too much about it. Pero if the smell is super unusual (like something's off talaga) or may other signs like baby is fussy, not eating well, or may fever, best to check with your pedia just to be sure everything's okay.
