Ay ito normal lang, lola! Pure breastfed babies talaga may unpredictable feeding patterns especially sa early weeks, sometimes they cluster feed, sometimes they skip, kaya basa ang breast mo kahit irregular pa lang. One of my mum friends said her baby was like that din, one day non-stop, next day chill lang, tapos balik ulit sa madaming feeding. The important thing is wet diapers at weight gain, so i-monitor mo yan, pero if you're worried or if baby seems uncomfortable or not gaining, best mag-check ng pedia just to be sure!
