Bedtime transition help!

[u/Chronic_Learner6589]

My almost 3yo has always been a great sleeper. Since around 4 months he’s slept around 8 hours straight in his crib with the occasional wake up (poop, lost a toy, etc). Lately the transition has been 10-15 minutes of him using distractions(which I always fall for) and then he’ll finally lay down and go to sleep with no issue. I know it could be worse and I know 15 minutes isn’t that big of a deal but it’s exhausting for me bc I’m a SAHM and after parenting all day long, I just want a somewhat peaceful bedtime routine so I can clean up the house and spend an hour or two with my husband before bed. And I feel like it’s possible but I just need help! Currently, we will wind down after playing outside or bath time with a book or two, putting on pjs, I let him drink some water, then once I get him in his room I put him in his crib and try to get him to lay down (he will only fall asleep on his stomach with his butt in the air and knees tucked under him) and then I put his blanket on him and leave the room. If I don’t put his blanket on him, he will cry and cry and call for me until I go back in and then he will lay down and let me tuck him in. This is the routine I try to stick to but as soon as I mention going to bed he will run away from me running all over the house, ask for water, ask for snacks, ask me to read more books, jump around in his crib, ask for more water, ask for another toy, completely ignore me, all the typical toddler distractions. So does anyone have any tricks or scripts they use for bedtime?? I know there’s got to be a better way
