Totally normal at the age! Mom of 2 under 2 here and they start exploring their mouth and senses more around 3/4 months and cause and effect
Thank you both so much for reassurance! ❤️
My lil one started doing this as well and still does sometimes, it’s his way of exploring! He’s starting to get to the stage where he realizes he can play with things!
My son just turned 4 months today and noticed he has been doing the same I think it’s normal I had mentioned it to his doctor and she didn’t seem to be to worried as long as he’s still gaining weight I think it possibly could be teething too but I’m not sure just pay attention to his gums
