Baby won’t sleep

Jessie

Anyone else in the same boat? My guy will be 7 months in 5 days and WILL NOT SLEEP. We start bedtime routine at 7 he eats at 7:30 and usually down by 8-8:15. Last night he was up at 10:40 back down at 11. Woke back up at 3:40 and was up until 5. Laid him down at 5 and back up at 5:40. I’m seriously losing my mind and this is not helping my PPD at all. I’m open to all advice. I’ve tried letting him cry it out for a half hour and he does NOT go back to sleep.
