My crazy boy

So my baby puts himself to bed around 7 we start the whole routine at 6 and he's out by 7. So I'll usually cook dinner for myself after I put him to bed. I swear he knows when I start cooking because within minutes of starting he's up screaming lol. Just been in the last couple weeks but ill have to pause everything and come put him back to sleep. I've waited and started later but without fail he knows.
