I'd love to hear about your experience!
DS2 has started sucking his thumb and I've had nothing but negative comments about it. He's 7 months now and it's really helped with sleep. It seems like a positive habit so far. I know it's bad for teeth and language development if they suck their thumbs for too long, but it is really such an awful habit that's impossible to break? What is your experience with your thumb sucking DC?
