My DS will be one in three weeks time, he was born 7 weeks early and only weighed 2lb 9ozs. He is the happiest little boy you could ever meet, his weight is now perfect for his age although he does still look small when next to children the same age but I suppose that's to be expected. I'm just a bit worried that he doesn't seem to be hitting his physical milestones, he can sit up for a while unaided but then just tends to fall to the side As if he has forgotten to support himself, he makes no effort to try and crawl and when I encourage him by getting down on floor with him and rolling a ball or a toy for him to crawl to he just lies down on the floor or rolls over until he gets to the toy. He also make no attempt to try and stand up or pull himself up in furniture. I have discussed this with HV who gave me some play ideas to encourage movement and we have been doing these daily but he doesn't seem to be making any progress
