DS2 is otherwise very happy and sociable little chap. He can roll both ways and has begun trying to push up on his front and bring knees up (but not very successfully).
The main thing that seems to be stopping him is some sort of reflex meaning that he arches back a lot, though sometimes it does just seem to be poor bablance. He was slow to lose his tongue thrust reflex too making weaning difficult - that only disappeared last week.
I wasn't worrying but have been really thinking about it recently rather than just assuming he'll catch up. Has anyone else got experience of this sort of thing? My HV is coming next week for a check but I just want to be reassured right now if you all think it's normal
