I'll have two babies with the same dad but I don't know what he looks likeGetty ImagesLucy, who didn't want to be pictured, is expecting her second child through a sperm donor "Growing up, this isn't the life I expected at all," says 41-year-old Lucy who had always imagined motherhood arriving in a more traditional order – a partner, a wedding, then children. Instead, her journey to becoming a mother began with IVF and donor sperm, a choice she made during the pandemic after she realised how much she missed seeing her sister's and friend's children. She jokingly told her parents that she could have a child on her own and recalls: "I expected them to laugh it off but they said I should and got excited about it."I wasn't expecting that reaction and it made me think I actually should do it," she told Radio 4's Woman's Hour. In her 20s, Lucy was engaged and always thought she would be a mother. When she found herself single just before her 30th birthday she says she went through a "real period of grief around what if that doesn't happen for me". Lucy's first son is now almost three-years-old and she is pregnant again with sperm from the same donor. She doesn't know his identity or even what he looks like."I look at my boy all the time and think how much does he look like the donor but it's impossible to know and it doesn't matter because he just looks like himself."She's excited to give birth to her second child and says it will be "interesting to see what the new baby looks like and whether they will look similar or have similar traits."The number of mothers deciding to have a baby solo is increasing rapidly. Data from the UK regulator of the fertility industry HFEA, shows that in 2019, 3,147 single women in the UK received fertility treatment with donor sperm.
