My son has stopped sleeping at night.

I mean, he sleeps but he wants to sleep on me. And nurse on demand.

He's big (23.2 lbs., 30 inches) and makes me ache from holding him in a chair. All. Night. Long.

His pediatrician wanted me to wean a month or so ago but I didn't. Now, kinda wishing that I had 'cause this nursing every hour or two stuff is KILLING me. The nurse told me last week at the well visit that he wouldn't sleep through the night until he was weaned.

So, few readers, I need advice. Got any? Should I wean? I'm not opposed to it just dreading the actual doing it 'cause this boy? Yeah, he loves nursing. How did you get your child(ren) to sleep through the night? Or, is it a lost cause and will eventually happen when he is 6 or so?
