Hi Emmie....I have only had success nursing one of my 2 children...My son, who is now 2 1/2 nursed until 15 months...then he started biting more than was usual. I had him nursing only at bedtime, to put him to sleep, and a couple of times thru the night...I had already cut him off thru the day. Anyway, after biting me twice, once on each side and I bled, I said "ENOUGH"!!!! The next night, I showered with different soap, used my hubbys shampoo, put on a hoodie shirt, gave him a little chocolate milk in a sippy and rocked him ...he fussed just a little bit, 15 mins or so, but never really cried, and he went to sleep...and I haven't nursed him since.
Any suggestions for you??? I would probably try giving him something really good to drink at the time you usually nurse, and rock, or sing or read a book, then that way he still gets his mommy time.
By the way, I still rock him to sleep....I can't handle letting him cry at bedtime...he goes down for naps on his own tho....Good Luck, J.
