Oo normal lang yan, lalo na if active siya during the day, ang mga babies kaya maging selective eaters kapag pagod or may teething discomfort, at parang gusto nila lang kunin ang gutom nila quick quick at tulog na! Pero since bigla lang siya nag-change at nagugutom siya ng gabi (parang umiinom lang tigil), maybe check with your pedia just to be sure everything's okay with the teething and kung sapat pa rin intake niya overall through the day. A few of us moms noticed ang aming LO rin naging picky sa gabi kapag nagsimula ang teeth, kaya hayaan mo lang if less alam mo naman na okay siya sa iba't ibang oras. Keep an eye on wet diapers and weight gain, kung parang okay pa rin, you're good na!
