To try to get him to stop sucking his thumb?
He sucks his thumb when "he's tired" which can be quite a lot.
I've total been and bought some dummies and have told him to use one of those instead and then when he Jo longer feels a need to suck his thumb, the idea is to get rid of the dummies.
It's only going to be when we're at home as I have some time off work coming up.
His thumb gets sore in winter and I think that 7 is old enough to stop doing it - but it isn't like I can cut it off!
Any wise words MNers?
