CC - I agree with the other girls too. Marley is at a lower percentile for her weight (compared with head and length) but MCHN wasn't concerned as she looks happy and healthy! Marley hasn't got any teeth (and they don't look like they are coming up either), has only just started to roll over and back, is nowhere near crawling and definately doesn't pull herself up on anything and she is over 7 mths old. Maybe once she is on the solids her weight will pick up a little. She looks and sounds like a perfectly normal, happy, healthy baby.
