4 months old first time mom

Hi mama! Normal lang yan, don't worry, yung rounded belly ng babies especially sa ganitong edad ay part talaga ng development nila, at ang ribs na nakikita mo is just how their body structure is ngayon habang lumalaki pa lang sila. A few of us mums talk about this kasi kami rin nag-alarm sa una, pero totally okay lang yan! But if you're still worried or if makikita mo nang may changes na unusual, best to check with your pedia para ma-peace of mind mo, they can confirm everything's perfect sa baby mo. Congratulations ulit sa little one!
