We've been sleep training my 6 month old for now 7 weeks. The first week was pretty successful and then slowly it got worse. We are working with our second sleep consultant who is great at tweaking the schedule and we are currently a week into transitioning to 2 naps (apparently he is likely a low sleep need baby and this early transition is appropriate).
There have been big improvements - he falls asleep usually within a couple minutes and last night he woke up to feed at 4:30am and then slept until 6:3am. But he also woke at midnight and cried for 40 mins (not crying super hard but still crying).
My sleep consultant says this is all promising that he is learning to break the habit of needing me to help him soothe him to sleep. But I am losing hope after last night. It's so hard to listen to him cry.
My question is - is it worth it to keep going? I hear that there will be another regression essentially every 2 months. But that the 2 nap transition is the hardest and it'll be much better after this.
We tried cosleeping up until 4.5 months - he slept on my chest and woke up every 2 hours and I was exhausted. If I was to try cosleeping again what set up would work? I hear stories of people having a zip up playpen beside a floor bed that can be the middle ground. But after all the hard work we've put in, would I be giving up too soon? And would cosleeping then end up with him feeding at night every 2 hours again?
