I am desperately hoping my ds3 will suck his thumb. He won't take a dummy and is very sucky. He is 8 weeks old. Tonight, in the sling, he did suck his thumb for a moment once I had removed my breast and he was still sucky. But he did not keep it in long.
My eldest sucked his thumb from 9 weeks old, but I can't remember how it came about.
My second had a dummy so that's no help.
I was wondering if there was an age when they are develomentally ready to do it? My ds3 is quite small, whereas my ds1 was big - not sure if this makes a difference.
