Almost 4 week old dd making 'lip-smacking' noises while feeding

[Picante]

It's really noisy! Ive had the latch checked and it's fine. She's had a cold - still snuffly - could this be what's making her make these noises? Is she getting into a bad habit or will she grow out of it?

Yes, I think it's probably because she has a cold.

Mine is doing this at the mo

The first one never did it.

It seems to be when she has had enough food and is just dozing and sucking sporadically. I have started taking her off when it gets silly!
