So tired...

Omw to the pediatrician Bc my baby just doesn’t sleep.. I know it’s not that big of a deal but he’s 5.5 months and still wakes 6+ times a night no matter if he eats 1oz or 10iz before bed,. I’m just fucking tired & work full time. I doubt his ped will say anything but I’m exhausted.. 2 monsters a day and that barely works. I fall asleep driving, eating, anything... ugh. any tips?
