My son hated the stroller when we first put him in it. So most of the time, my husband had to carry him and I followed with the empty stroller (feeling very silly). However, we continued to put him in it for short spurts every time we went out (for as long as he would tolerate it) and he gradually got used to it. Also, he was much happier in it once we were able to put the stroller up into a sitting position (when his neck muscles were stronger). So now, as long as he is more or less upright and in motion, he is happy to be in it.
