Postpartum insomnia 😭😭

Hi lovely ladies, so my son is 3 months old and sleeps well. Only issue is, I can’t fall asleep or if i do i wake up every hour. No one talks about postpartum insomnia, all my other mum friends say they fall asleep when their head hits the pillow.

I am exhausted so why can’t i sleep? Is this common? Is it hormones?

Im speaking to my doctor this week to hopefully help get this issue sorted 😭 Any other mamas who went through this? If so please give me some tips?
