Hello po! Okay lang yung yellow poops, that's actually normal sa breastfed babies, at ang amoy naman ay expected talaga, so hindi ka mag-alala doon. But kung concerned ka talaga or gusto mo lang ma-confirm with a professional, better to check with your pedia para ma-ease your mind, lalo na as a first-time mom! A few of us moms din natakot sa simula with these things, pero once na nag-check kami, ok lang lahat. You're doing great, mama!
