G.D.
Knowing you and the situation I agree with your stopping. I've seen the sitaution, you've done a great job and nursed her for much longer than most people last. She is getting nutrition for foods now and I know your not giving her junk food. She's fully capable to doing without. I don't think it's about it being tramatic at all! Again, because I know you guys, I feel very confident that she is only trying to control things.
Honestly, I would take the time when you don't have to be waking up early or for any specific time. Also using the time to let her scream it out in her own crib in her own room. If she bites, slaps or anything, in her crib she goes. Trust me, it's NOT easy. Not easy one bit and very hard and stressful especially for Mom. I think it has to be something both parents are on board with and both willing to do what it takes.
Once J and I were in accord with stopping it took T no time at all to get into the swing of things. She picked up pretty quick and never looked back.
Best of luck love.
Definitely talk it over with Daddy.
And remember, you did a GREAT job! After 2 yrs of nusing you reduce the risk of breast cancer by 40%...your over 2yrs now.
