As some of you know i'm concerned about DS1's behaviour and development to some degree. Anyway lately he's been getting scared of random things, he was watching a brainy baby dvd where there are shapes and colours and he just freaked out when a picture of a triangle came up...but he loves triangles, it just seemed to be THAT particular triangle. Anyway there have been other random fears and i know its normal at his age to start getting fears however today he just flipped out. Dh does this thing where he walks DS2 around the house and pretends DS2 is chasing DS1... usually ds1 will scream and get a bit scared but its more of a play thing really. Anyway the last few days DS1 has become terrified of DS2 crawling. If DS2 starts crawling towards me or DS1 he just flips out. Today he wouldn't let go of my legs and kept screaming at DS2. He was genuinely terrified of him. Anyway DS2 started crawling towards me and DS1 wrapped his arms around my leg and literally tried to crawl up me.. and then he bit me, hard on the hip. He's never been a biter and I think it was out of fear and frustration more than anger. I screamed because it really hurt and shocked me (it broke the skin) and poor DS1 got a fright from my reaction. I guess i'm just curious to know if its normal for a nearly 3 year old to get so scared of something (or someone)?
