My boy started rocking on hands and knees at 4 months then a little bit after 5 months was crawling :) so he had about a month of pre crawling give or take!
6/7 months lol and even that was slow. she would do the same and shuffle backwards 🤣🤣 now she’s 8 months and already pulling herself up and standing ! it happens so quickly lol she’s crawling all over the place now
Same my baby is 4 months and she just kicks and wiggles until she turned a whole 180😭
