I am in the same boat, DD is 18m and I really want to stop now for many reasons. She is very attached to me (literally) and has been a terrible sleeper so I am worried she'll get worse if I try to stop. I am really looking for a plan I guess!
It sounds odd MrsMcJnr but you might see an improvement in sleeping if you stop feeding at night - that's how it worked for us anyway. Theory is that they learn to settle themselves back to sleep when they stir at night instead of relying on you and your boobies. That's the theory anyway.
