Lagging Behind?

Mummy is getting a little paranoid over Baby Matty not being able to wave bye bye. Never really came to mind until Dr. Chan casually asked if he was able to do it. To make matters worse, Mummy found out just yesterday that most of the babies in the forum board are able to do it when they are seven or eight months. Oh dear we are lagging way behind.

Actually Matty was able to do it when he was three months old but he somehow unlearned that when we failed to practice with him on a regular basis. Same thing with shaking hands.

Daddy and Mummy's mummy retorted that Matty being a bright boy knows how to do it... but he just refuses to. Talk about self-consoling
