There is a smart crib available in the market named Cradlewise which has rocking motion “up n down”.
Ours did the same last night 😵💫 he’s definitely teething though. We use the hyland teething tablets nighttime ones! They work really well. Ours is definitely teething and going through a sleep regression so maybe your little one is too? 🫶🏼
Considered the fact the he might be teething? That causes a lot of discomfort. If not then maybe colic. I’m experiencing something similar with my daughter who just turned 6 months❤️
