My 4 mo. old wants to be held all the time. Maybe I held him too much when he was younger (and lighter) and he thinks this is how life is supposed to be but now that he weighs 17 pounds, I just can't do it anymore. We have a bouncer chair, swing, step-n-play piano, and bumper jumper and he likes them sometimes, but usually he hates them all and cries. I've also tried laying him on a blanket- for example in the kitchen when I am making dinner so that he can see me, but that doesn't work either. I'm totally out of ideas. Any suggestions??
