The best advice is take one step at a time and go with the flow. Don’t be too stressed out on the milestones and most importantly, don’t compare and don’t listen to your friends saying all the “you shoulds or their lo blah blah”.
I’m a more chillax (lazy to be blunt) mom so I don’t really read a lot of milestones or whatever phase so tbh, I don’t know which month is supposed to achieve which milestones etc. All kids will grow up differently at their own pace. As long as healthy, don’t worry too much 😊.
