my 4 month old is so hard to get to sleep. when he hold him he archs his back trys to kick off me and arms try to grab everything around. my babys eyes are closed the whole time. he does this going to sleep for naps and for bed. i am becoming so frusturated spending hours a day waking around my house rocking him but he wont go to sleep any other way. if i set him down he screams. 3 weeks ago he went through what i thought was his sleep regression and it ended and now he slreps a lot better once i get him to bed. any tips or tricks? is this just more sleep regression?
