I am nursing two babies. The older one might be 27 months old, but she's still a baby, relatively speaking. The other one is nine months and his only source of nourishment is my milk.
Yes, I realize it's not the societal norm to nurse even one baby past a year, but I don't care what society thinks.
My babies are receiving human milk from their mother, the way nature intended. They are being allowed to nurse as long as they desire to do so, per the World Health Organization's recommendation of two years or longer, as long as mutually desired.
Any other mammal nurses and nurtures her offspring. She also keeps her young close. I co-sleep with my babies, and learned quickly on night one with my oldest that he didn't want to be away from me. Every time I would put him in the little bassinet in the hospital (with heated blankets even), he would begin to whimper/cry within minutes. I finally decided to just bring him into the [gasp!] hospital bed with me and I snuggled up with him and he slept very well. I did the same with #2 and #3, right from the first night in the hospital. The staff never said anything. And if they did, I would have told them it was my choice to safely co-sleep with my baby.
I have let loose of society's pressures to separate and create an independent child from the beginning. I don't believe that society follows Mother Nature's intentions. I follow my mama instincts and so far they've been spot-on. What I have created are children who are so secure and safe that they are not afraid to step away from me when we do go out because they know I am right there for them with open arms should they need me. I will always be their mama.
