i think your baby will be able to crawl forward within 2 weeks, just like my girl ^^
my baby's super movitation is my i phone !!!
i download some baby apps in my iphone, she loves it so so much !
u should put the toy close to him,just barely can't touch it , if u put that far away, he will lose interest to get it
also if he cries for the toy, use other way to distract him, make some noise or funny face, just let him forget the toy
baby is very easy to be distracted !
try again and again and be patient ~
i didn't force her... but i will let her play on the mat law... she will turn around on the whole mat.. we also taught her how to crawl few times... now these days.. she starts crawling la (as she can hold up her pat pat and crawl)
