Sleep regression? Crib introduction? Why no sleep? 😫

This will be me and my husband today I’m sure.

Not sure what happened last night with our daughters sleep. Usually she can sleep a solid 4-7 hours each night. But last night? Last night she was up almost every 1.5-2 hours. And when I’d get her to go back to sleep, she’d pop her eyes back open. I did start having my MIL start putting her in her crib for at least a nap a day this past week. Plus I don’t think at least, my daughter didn’t go through the 4 month sleep regression. We’re 5 days until she turns 5 months.

Wondering if the crib introduction, a slight sleep regression, or just a fluke occurred? But like I said earlier, this will be me today 😴
