4-6 months

Everything goes through the mouth

Mouthing objects is one of the ways babies learn

The Millie's Team By The Millie's Team · Parenting Notes

Around week twenty-two, almost everything your baby grabs ends up in their mouth. Hands, toys, clothing and even your fingers are all fair game.

What is happening

The mouth is one of your baby's most sensitive places, with far more nerve endings than the hands. Mouthing is how babies find out about texture, shape and weight. It is a key part of sensory learning, not just a habit.

Is this normal

Yes. The mouthing stage is normal and lasts a long time, often well past the first birthday. Extra dribble during this stage is also very common, even if teeth are still some way off.

What to expect next

Mouthing usually continues for many months and will quietly fade as other ways of exploring take over. There is no need to discourage it now, only to keep the things within reach safe.
