So ever since my little boy was two months old I started sleep training him where I would put him in his Rock and play and he would put himself to sleep. the first time I started he would cry for like 10 minutes but I would go down there check on him tell him it's nap time and he will go to sleep and then he got to the point where he put his self to sleep like after 2 minutes of crying. That was amazing!! Now he hit three months and his cry is now more intense he screams now and it's not as easy to put him to sleep himself to sleep. I'm just not sure what to do... Just keep letting him cry himself to sleep or hold him and rock him to sleep.?? Today his crys are so sad and they hurt my heart... Any advice?

The pictures is just for fun.❤
