My son is 10 months old and until a week ago woke up anything from 4/5 time a night to over 15 times a night - no joke...!!!!
I've survived on average 2/3 hours of broken sleep a night
I crashed my car a couple of months ago with my son in it , I drove straight into the back of someone purely because of long sleep deprivation , I was in a daze. My son ended up in A&E
I was dead against ever leaving my son to cry and instead the minute he cried I would go get him from his cot and BF him back to sleep, often only a few minutes if that. Clearly more a comfort thing rather than him needing milk as he is on 3 good meals a day
Anyway last week I finally snapped , also scared it was going to affect his development as he was not getting decent sleep either
Anyway I put him to bed and as normal he woke this time I never ran through, he moaned and cried a little and low and behold 20 mins later he was asleep this carried on through the night but every time he cried I left him and he was back asleep in a few minutes , next same again but he woke less times
We are now 7 days in and last night he slept from 6.30pm to 6.30 not waking once
My sons sleeping "issues" were created by me.... Running through to pick him up, breast feed him etc
I wish id left him alone to settle back to sleep months ago.
I thought I was doing right but what I was doing was creating a situation that meant neither of us was sleeping and he could of been seriously hurt (car accident)
So my advice would be just try and leave him to cry a little bit it might just be you are causing the sleep issues like I was.
