What a cutie Jaclyn&Serena!
My 4 year old crawled at 4 1/2 months but only walked on his 1st birthday (at his party - it was so sweet!!)
My poor lil bubs Ty Ty is 9 months old and still struggling to get his crawling into gear. He gets himself into proper position but then can't move. Poor angel has been trying to do this for about 7 weeks. No amount of crawling on the floor by Will & I can make him do it!
