Mama, those bumps could be a lot of things, swollen lymph nodes, skin tags, or just how baby's anatomy is, pero importante talaga na ipakita mo sa pedia para ma-check niya properly kasi nakita mo na since birth pa lang. One of my mum friends had something similar and the doctor said it was nothing serious, pero peace of mind is priceless diba, especially with first baby! Kung bumilis ang growth or naging painful, definitely rush to the clinic na.
