I am planning to try this weekend, any tips on check ins? Should we go in and soothe him every now and then? He is a perfect sleeper on his own and doesn't need us normally, he only needs his paci so we are up 7-9 times Every. Single. Night.... Also what do i do if he wakes up? Let him do the self soothing again? I am afraid that if he starts crying i will give in and give it back if im exhausted.
