i couldnt agree more, kids do things SO differently and at such different times, if she was 1 maybe id be looking into it, but 8 months would be pretty normaly i think. DD didnt mind tummy time but didnt crawl till 10 1/2 months, and even then it wasnt a proper crawl....one leg bent one leg straight...looked very funny, but only did that for a few weeks and was walking by 11 months (well...wobbling) and is now 2 and pretty well rounded .

I remember when my DD was tiny and i was worried about milestones, a friend told me ''by the time they are three they have all pretty much got the the same level and it doesnt matter who did what first then'' i always remembered that and just let DD do her own thing! hugs to you.
