My 4 months old refuses to sleep at night and we need help! He slept for under an hour last night between 9:45 and 3 am. We tried holding and nursing, side lying to nurse, rocking, bouncing, and CIO for about 10 minutes when he woke up his brother. Crying is not an option because his brother is a light sleeper and once he wakes up MOTN he strugglesaid to settle back down and one of us ends up in his room the rest of the night. He normally will give us the best stretches in the RnP but he's starting to outgrow it so we have been trying the mini crib next to the bed and co sleeping. My older boys would usually at least sleep if they were in bed next to me but not this boy! I know my other two had trouble sleeping when working on milestones and he has been trying to roll and sit up but this has been going on for weeks now! Any suggestions? We need some sleep!
