Is the biological mother of a surrogate baby that she delivers, even in cases where another egg was used? One thing I hate hearing in the surrogacy debate by pro-surrogacy folks (who like to minimise the connection between mother and child and the effect that separation at birth can have on both) is “the surrogate has no biological relation to the baby” in cases where an egg other than the surrogate’s own were used. Of course she has a biological connection to the baby. She doesn’t have a GENETIC link to the baby - no. But biological? She has about as much of a biological connection with it as she would her own genetic child. The baby is quite literally made of her. The genetic material of the egg may predetermine baby’s genetic make-up to match that of the intended mother’s egg but that is such a shallow link compared to the nurturing happening during the pregnancy. It's the surrogate mother’s body building and nurturing that child. The mother’s body will likely forever retain snippets of the child’s DNA - particularly traces of Y chromosome if she carries a boy. Everything the mother does or eats or feels will influence that child. The baby knows her smell and voice and as soon as they are born they seek her, and they will feel stress at being placed into a stranger’s arms rather than mum’s immediately after birth. It’s completely ridiculous to say there is no biological connection between surrogate and baby. What’s more of a connection, really, to a newborn baby who has no concept of themselves other than the birth mother who is all they have ever known? Is the baby bothered about a mother who makes up half of their DNA but who has been on the other side of the world since their conception and is going to lay claim to them through a financial transaction? Or is the baby instead going to crave the presence of the woman who has grown and nurtured them? The surrogate is mum and the baby is going to need her post-birth no matter how much people want to ignore that.
People like to say “DNA is nothing” in the context of the love between step-parents and their stepchildren, adoptive children etc, and that’s rightly so. A genetic link isn’t what makes a family. But in the case of surrogacies, this is all completely thrown out of the window and the idea of a surrogate mother bonding with her baby (because it is her baby…) is inconceivable because she ‘isn’t even related to them’ despite literally creating and birthing the child.
