Constipation

Aww mama, that's so common when babies switch formula, ang system nila talaga need time to adjust! Definitely bring it up with your pedia kasi may specific things they might suggest based on kung ano ang new milk, pero in the meantime try gentle belly massage in clockwise motions and make sure baby's getting enough water (if formula-fed, the water in the formula mix should be enough na). You're doing great being attentive to these things, first-time mom worries are real, but you're already on top of it!
