What am I doing wrong?
My LO is 4.5 months old and I started sleep training 8 days ago.
The first 5 days went very well and he was on schedule 1.5/2/2/2/2.5 with 3h naps but on the 6th day on this schedule, he wouldn’t settle in his own bed at 4am and he already woke up once before this.
So for the 7th night I switch to schedule 2/2.5/2.5/3 with 3h naps, the day naps improved on this schedule and the night improved as he only woke up at 4am but took an hour to settle him in his own bed but then he slept until 7:20am in his own bed
So i then stayed on the same 3 nap schedule but reduced the naps to 2h 45m. So this was last night, he slept for 5h, he woke so i fed him, then straight back down, he settled himself to sleep but after an hour he started crying, I left him for 10 mins but it was escalating so I put him next to me and then I transferred, then again after 2h woke crying again and the cycle went on. He did eventually settle and slept until 8:40am
At the start of the night, he falls asleep independently within a few mins and naps are no longer a battle on this new schedule.
Do I need to the Ferber method during the night? Or is he under or over tired?
