Oh mama. I just wanted to let you know I too, am so sorry for your loss. Words cannot decsribe what you must be going through right now.
I'm just wondering if your daughter is picking up on the grief at home and maybe having a little bit of neediness because of that, and compounded with extra milk, thats why she is so needy to nurse. On the other hand, my son is 2, and if there was suddenly mooore milk he would be THRILLED! and too would take full advantage.
I'm not trying to wean my son (yet) but I have noticed that if we go to the mall and he is playing with kids in the play zone he doesn't ask to nurse so much. Or if we are somewhere he thinks is super swesome to play, he doesnt ask as much. you get the picture.
I know from experience that sometimes nursing a toddler is VERY draining. It can also be a lifesaver at times too.
Maybe getting out of the house will be good for both of you. Maybe you could start her in a mothers day out program? That might give you a much needed break from nursing at least for a few hours and get her out there playing with buddies too.
We are here for you.
