my dd is not really standing or cruising yet and seems to have little real strength in her little legs. The specialist has ruled out cp, and suggested doing some blood tests etc for the absence of muscle enzymes. anyone else any experience of this? i can lead dd around, holding her hands(and she puts her whole feet flat on ground) but after a while she just buckles her legs. an mri scan has been mentioned as a possibility in 3 months' time but that involves a general anaesthetic so not keen. DD appears fine in all other respects.
