no need to worry
my bb just started to crawl this week, she experienced all you described for about 3 weeks (吉"起pat pat, 入後波, etc). Then one day I noticed that she crawl to get her favourited toys........my slipper now she crawls freely....especially when there is a toy far away that she wants to take :mrgreen:
Yes yes, same experience as funnyjenny. Try to attract baby with their most favourite thing, no matter it's toy or food, then they will crawl towards, not backwards. Need be patient and take time!!
