We're expecting dd3 in September and have a couple of names we like but one is the same initial as dd1 and the other the same as dd2. Do you think it matters? They also have the same family middle name so they would have exactly the same initials if we used either name.
my pa has cousins where the dad is called Martin, his wife is Marie, thier four boys are, Malcolm, Michael, Maurice and (little) Martin; they also have two daughters who they called Michelle and Susan. Why would you do that, you, your wife and 5 kids bames begin with M and then the youngest comes along and you call her Susan.
As for your baby, it won't be a problem so long as you make sure the middle initals are different.
All my 3 have middle names beginning with J.......not purposely, it just seemed to happen with my first 2 Kyle Jordan and Liam Joshua then when I got pregnant for a 3rd time my nana told me I had to keep up the J tradition so Yasmin Jade it was
