We have an activity mat for my 2.5 mo old. After recently reading the Baby Whisperer I realize that we were over stimulating my son with too many toys, shaking rattles at him, etc. We have started hanging just one toy at a time, but he is still VERY excited. He coos loudly and kicks his arms and legs strongly. He can keep this up for 20-25 minutes (after bf and diaper change for a total of about 50-60 minutes awake). Then his kicking will slow down and he gets fussy. We immediately swaddle and take him to his crib to begin soothing, but he always goes into a hysterical, back arching, squirming fit when falling asleep and it is very hard to calm him. So my question is - is all that kicking during A time normal for 10 weeks or does it sound like it is too much for him?
