Parenting is full of grief.
Adoption, relinquishment, loss, abandonment, neglect, abuse, are full of grief.
Infertility and miscarriage are full of grief.
And no one type of grief can trump the other. 

I’m goin’ out on a whim here by saying that I am totally against this product and all it stands for…convenience in baby feeding? Everything that I have stood for since adopting my first son has been attachment, because every adopted parent HAS to focus on attachment. Do biological parents just not worry about it?
