The last few nights, my 2.5 year old son has woken up crying out for me (he usually wakes up at least once during the night, so this is normal for him), but when I go to him, he pushes me away shouting that he doesn't want me, then he throws himself on the floor and won't let me touch him. My husband has to come in and pick him up, and then DS immediately changes his mind and wants me to take him. Is this normal behaviour..? My husband sometimes works night shifts, so I'm not sure what to do next time DS wakes up crying and refusing to let me comfort him.
