Leap

6weeks, 4month (hit at 5 for us) and 8-10 months. I’d say 6 weeks was the worst sleep wise, then 4month. 8-10 months was hard bc they learn to sit/stand and spring up everytime you lay them down. They have to learn to lay back down on their own and it’s frustrating.

4/ 4 months by far cause of the sleep regression. Currently have a 2.5 month old daughter (my second) and dreading it.
