DS is 9.5 months and has been sitting up on his own since 6.5 months. Until recently he has been quite happy to sit and play with various toys within his reach for as long as I let him. He now seems to be getting increasingly frustrated when he can't reach toys or when I walk away from him. He tries to lurch himself forward doing a 'bum shuffle' but never manages to go anywhere. The harder he tries to move, the more frustrated and upset he gets so I end up picking him up just to calm him down.
I try to give him regular tummy time but he's never been a fan of it. If I lie down with him and show him various toys and keep him entertained he'll be okay for awhile, but soon gets cranky if he spots a toy he can't reach (Isometimes will deliberately put a toy just a bit in front of him to encourage him to move forward). He can push his front right up but is yet to pull his knees in and put his bottom up in order to actually crawl.
I try not to worry especially since I know that crawling is no longer an 'official' milestone given that some babies skip it altogether and go straight to walking. DS has never been advanced in terms of gross motor skills, he was late to bear weight on his legs (6 months) and I ended up getting his hips x-rayed just before that to check if there was any problem (there wasn't... he stood up perfectly on my lap the day after the x-ray...!) He's also not pulling himself up yet from lying to sitting or sitting to standing. He's been able to roll since 4 months but doesn't do it a lot.
I do think that DS is probably a bit more advanced in other areas such as language (babbles a lot and can clearly say mama, dada and duck!) but I still worry when I see babies 2-3 months younger than him crawling and pulling themselves up etc...!
I'm thinking I'll give it another few weeks before checking with a Dr but keen to hear others thoughts and experiences...? Is there anything I should do to help or encourage him?Or is it something he'll just need to figure out on his own?
