I think it can, but not necessarily be something that could possibly come back to slap the mother in the face years down the line. It depends on the child, we are all a combination of inherited characteristics so there's unpredictability about reactions or character traits that may be completely alien, given those composite of genes that go into making us who we are. I've seen interviews and read about very angry IVF adult children.
I have a friend who grew up never knowing her father, she felt her mother had purposely withheld that information from her, plus her mother told her birth had ruined her life. My friend through Ancestry and her DNA results has now made contact with a host of half brothers and sisters she knew nothing about, plus the back story of the circumstances around her birth. Her now dead mother, was training to be a nurse in Jamaica, her man had deceived her he was already married and he then abandoned her, at that time she had to give up her nursing aspirations. Anyway, long story short of late she has made contact with all her half siblings who have welcomed her in open arms, that has filled an enormous void in her life, she had a very unhappy childhood. Her mother came to England married a man, had more children,who have now cut her off, my friend was regarded as a cuckoo in the next, step father was abusive to her. I was so happy for this unexpected development, albeit coming later on in life. On the other hand, a similar situation, my hairdresser telling me about a family funeral she had to attend where her father, who again had abandoned her mother and her sibling to set up home with another woman, at this event she told me there were several half siblings. I think I said something along the lines of "that must be nice for you having them" she said she wasn't remotely interested in them and had no intention of keeping in touch. I think she just saw them as a bi-product of the misery that her father had inflicted on her mother. No two scenarios will have the same outcome.
My husband has/had two children from his first marriage, unfortunately his eldest died. We were all devastated when that happened, including my two who were teenagers at the time, a much loved big brother. However, I'm really pleased that they have a very close relationship with their half sister, although none of them ever refer to the "half" she's always "sis" if they don't use her actual name. Although I know she was very close to her full brother, they were only a year apart so his loss to her was immense. I think having two younger brothers has at least provided her with the feeling of "I still have siblings". I remember calling round to her house when she moved fairly near us a couple of years ago, to find one of my sons helping her shifting the furniture around, they both have long telephone conversations with her, longer than with us I believe
My younger son is so like his half brother not only in looks but mannerisms. Last week when she called in, she was looking at her dad's recent birthday cards and when she read his card, she said she can't get over how similar his writing that of her older brother.
