My son was up until 4am yesterday and woke up at 12pm. 😩 He hasn’t napped today and it is 9:30 so hoping he goes down relative easy soon and sleeps through the night because I am so freaking exhausted. Only slept 2.5h before work yesterday then slept from 6am-9:30am and then from 3-6pm. This broken up sleep is just.. totally not helping.
