My DS is just over 2. Whenever I take him out to the shops or play group he has a tantrum and lies on the floor screaming. Take for example.. I went shopping yesterday and he didn't want to go the way I was going (walking) so he lay on the floor and screamed NO! In the end I had to pick him up and carry him until he calmed down. I then went to the supermarket and he spotted something he liked.. I asked him to come with me and again another tantrum. I had to carry him under one arm with him kicking and screaming until we got to the car where I had to physically hold him in his car seat to put his straps on. The odd thing about this is, he only ever behaves like this when he's with me. When his grandparents look after him, he is well behaved! What am I doing wrong?!
