I LOVE the name Maddy and it is the top of my NameList.....just need to persuade DH if we ever have a girl. Although Mums can be great they can be horrible too! I cant explain mine but she drives me up the wall and was SO opinionated about what we called ds. As was my Dad. My thoughts are that they had the opportunities to call their children whatever they wanted and we should be allowed to as well.
If you dont use Maddy I think you will really regret it and as you and dh have agreed on it go for it!!
It is the biggest insult in our house if my dh says I am like my Mum too.
When my sister was born 18 years ago, my Gran walked into the hospital and said to my Mum, 'Amy? What sort of name is Amy? Id only just got used to that other name you had chosen! (which was Abigail!!) You would think my Mum would learn!!!
