DD still dribbling constantly at 2.4yo

[fadingfast]

DD was a very dribbly baby, which we of course always put down to teeth. She has had all her teeth for a few months now, but still seems to be REALLY dribbly. Some days are worse than others. She sucks her thumb quite a lot, so I don't know if that is making it worse, but she dribbles even when not sucking her thumb.

Is this anything to worry about or quite normal?

I don't know if its normal, but my 2.9yo DS also still dribbles a lot-not a thumb sucker, good speech, doesn't have his back teeth yet-which should be arriving soon (and may be the cause of the drool)

I'll be watching with interest!
