A friend of mine fed her DS til he was 3 & she said weaning was hard. The only reason it happened at all was because she had to go away for 3 weeks. When she got back, she just said 'no more, boobs are gone' & he was fine with it.
You can't really just pack up & disappear for 3 weeks though can you.

You've done great! I'm starting to have those feelings already. Only coz we still feed like a NB!

Maybe just explain it to him. He has to be a big boy & big boys don't need booby anymore?? I'm not sure, sorry.
