Is my baby too young to self soothe?

We started letting our daughter learn to pify herself since she was 2 or 3 months of age. It has really helped us in the long run, because now I can take her and lay her down any time she is tired. If she's not ready for bed, she will play until she falls asleep. It may be hard to do, but you might need to let your little one "cry it out" Leave him in the crib for a few minutes and if he doesn't stop crying then go give him a paci, blanket, and/or stuffed animal. (Our daughter always has to have her blanket and her stuffed monkey) When you go in, don't pick him up, and don't give him too much attention. It may take a long time, but eventually he will learn to pacify himself until he falls asleep. Maybe this can help you!
