Physical Growth & Development Guidelines: 

2 - 4 months

 These data of boys and girls height/weight are different from
Singapore rule. This is based on the Guidelines and Instruction for Maternal and Child Health in Japan.

Infants 2 - 3 months:

Infants start to find their voice

Infants start to follow moving objects with their eyes. They will be able to turn their heads towards noises and voices.

Head control will be better and babies will try to lift their heads when placed on their tummies. They will start make "ah-ah" and "oh-oh" noises.

Infants will start to put their hands to their mouth and some may start sucking their fingers.

Important Tip for Mummies: 

Infants will be much better at feeding by this time, and a feeding rhythm may be created.
