My son was really bad for this and would make himself throw up, he grew out of it but it did last a few months unfortunately. We tried loads of things to try and get him to stop in the end just had to stop him distract and wait it out
My boy did this around that age too the more you react the more they will do it too so just try not to react and they will stop eventually, could also try distracting too xx
My son did this around that age too. He randomly stopped. I just tried to distract him to get him to do something else
My son did this for a little while around that age. It's normal sensory exploration. It bothered me a little as well when he did it, but I would usually say are you hungry? Do you need something in your mouth? and I'd offer food or a teething sensory toy. The phase only seemed to last a few months. I tried not to being too much negative attention to it, as to not have it persist. 🤪
