Kell, I really don't think you have anything to worry about, I bet Jesse is doing other things and that is where all his brain power is going. I read that if bubs develop one skill then other ones fall by the wayside till they have got that one skill happening. All these baby mags/books are a shomozle when they say baby should be doing this or that,etc, bubs develop at all ages. Do you take him to a paediatrician or clinic nurse for his 12 month check up - I am sure they will be able to put your mind at ease. I remember all the bubs at the Mums and bubs group I go to were crawling and I was really panicking because Rylee wasn't and then one day out of the blue she just took off. I am sure Jessman is absolutely fine and will give you a big surprise in the next week or so!
