Ex H and I have 3 dc, we were married so both DC and I had his surname. We divorced and I met DP.
I reverted to my maiden name and DP and I had a child. Our child took his surname.
DP also has an ex wife and child who have his surname.
DP and I are not married although I would like to be. I am now pregnant again and have been considering giving the child my surname.
It may sound petty hate not having the same name as my DC, especially as ex h's new wife and DP's ex wife all have the same surname as my DC. I feel left out.
Would I be unreasonable to change my name by deed poll to that of DP or ex H? Perhaps I'm being hormonal?
