Read “solve your childs sleep problems” by dr ferber. I used his method (online you will find different versions of this “ferber method” ) at 8 months with my youngest son. That is a good age to sleep train! My son adapted pretty quickly. It does involve crying... but the younger the baby, the less crying (cause they are more tired and can’t “fight” to stay awake as long as older babies). You must have a routine in place... mine is jammies, nurse, brush teeth, give puppy lovey, sing song (twinkle twinkle), put in crib. First three days are hardest... then for a couple weeks he would cry like 30sec-1min once in the crib. Now he just rolls over snuggling his puppy and goes to sleep... sometimes even making cute coo’s and such. Good luck momma! Transition is always hard but the earlier the easier for sure! (The book explains how to do the middle of night feedings too. Strongly recommend.)
