Timbang ni baby na hindi nadagdagan

Hi mommies. Normal ba na hindi nag gain ng weight si baby 1 week after she was born? Yung weight nya po kase nung pinanganak ko sya same parin ngayon na 1 week old na sya. Unlilatch naman po kami at feeding time nya every 2-3hours. Nagppoops at ihi din naman po sya. Salamat po.
