I've felt icky sometimes... I had very little exposure to older nurslings before... well, LLL. I would be totally freaked out with my 2 year old nursling if it weren't for LLL. I've gotten over most of it. It helps that she stopped fondling me so much! Now its reversed: when my husband shows interest in them, it seems like infantile behavior.
I have a little secret over here for nursing alternatives... It must be used VERY carefully, but lately, Halloween candy wins over nursing every time!!! Not exactly a healthy alternative, but a tiny piece of candy twice a day has gotten my little one down to three nursings a day; wake up, nap and bedtime. But I don't want her to replace the comforting part with the candy.. Its the boredom, hungry and routine nursing that I targeted with that. Shhh. don't tell!
