They probably are teething once they start putting stuff in their mouth is definitely a sign for teething. Drooling is another sign and chewing on stuff too (like mine will chew on the metal part of her pacifier clip instead of the pacifier lol).
It's not necessarily a sign of teething. Young children explore the world by mouthing things.
My girl licks EVERYTHING. If she can get it to her mouth, she's gonna try to lick it or chew on it. I think it's about exploring new sensations. It definitely means they are interested in their surroundings! Sounds like a healthy, curious baby to me. 🥰 I just keep the unsafe licking things out of reach. Lol.
Yesss this lol my LG is always playing with her tongue
My baby does that! I think it is normal
My son's 5 months as well as does this too I think he is just exploring everything but he has his two bottom teeth
