We had a routine of having him sleeping in his crib (bed by 630pm, up at 2am, 4am, woke up at 7am) then I went travelling twice with my boy. We got in the habit of cosleeping and he was waking up crying every 30-45min for cuddles. Yesterday i shortened his naps to 2x a day then kept him up longer. Did ferber sleep training at 7pm (checked him after 5 min of crying, then he fell asleep 9 min after). He only woke up at 11pm, 2am, and 6am woke up at 8am no crying! I just fed him. Its so nice to get a few hours of sleep in a row again 😁
