My baby is 18 weeks (a little over 4 months) and he STILL doesn’t sleep through the night!

His doctor said that he should be sleeping from 6 to 12 hours, but he wakes up every 3 hours as if he was a newborn baby!!!!

I’m so exhausted and it’s affecting my mental and physical health

Is anyone else suffering from the same thing?

I followed EVERYTHING in the books or online about how to get your baby to sleep...etc

Nothing works!

I know that every baby is different

But I’m really sleep deprived and exhausted it’s not even funny
