Yeah I think so too^^ because my daughter crawled at 5 months and my nephew crawled at 8 months.
My son crawled at 8 mo and pulled himself up at 10 mo, yes, every baby is different, girls do everything earlier than boys.
All baby's are different my daughter has been crawling for about 2 months n she's 7 months. She's now to the point where she uses the cribs bars to pull hersef up to a standing position. She tries to stand with out help but has trouble with balance to stand on her own
