why is he leaning backwards? he can sit well on his own right? u can put his fav food or toy in front of him, jus a little beyond his reach. will he try to reach for it? if he can lean fwd to reach, put the toy or food on the table in front of him. if he really wan, he will lean forward, put his hand on the floor. u got to guide him. keep encouraging him. smile, cheer, edge him on. jiayou jiayou. clap for him. let him know u r happy that he's trying. LOTS OF ENCOURAGEMENT AND PRAISES! if u keep getting unhappy with all his attempts, he also sian liao, dun wan to try. get it?
as for sit up, Jo dun sit up fr lying down. she flip and push herself up and sit. the other way u can do it. when Teng lies down, let him hold ur forefingers or thumbs, gently u pull him up to sit. that will exercise his stomach muscles. i did that a lot when Jo was abt 4-5mths old.
exercise his leg muscles. like cycling in the air, open and shut etc. it'll help i believe.
dun rush him.. give urself and Teng 5-10min ea time. if not u get frustrated, he gets stress and cry.
