My little one is 2 months old will be 3 months October 7th. When did you ladies start sleep training your babies. My little one use to sleep 3-4 hours at night but last few days she sleeps about 2 half hours wants a little milk and goes back to sleep. She does sleep in her crib but unless she in a deep sleep will wake up soon as you put her down. Not sure if should start trying sleep train her now or wait or let her figure out her sleep on her own. I plan on asking her doctor but was curious what you ladies did or plan on doing?
