A fellow 'working Mum', said she felt guilty about it, and asked if it was bad for 'bonding'. I pointed out that the idea of pre-schoolers needing a SAHM and bonding was promoted after WW2, to get wives back in the home freeing up jobs for men and single women. Women who needed to work to provide for their families were criticized. But it was ok for a rich woman to employ a nanny so her social life was not disrupted.
When I was pregnant, in 1987 I had a rule about not buying any clothes in pink or blue, and no dresses until the baby was born. (I did not want to know my child's gender until the birth, and was told by the sonographer : 'I'm not allowed to tell you.') My mother was surprised by my rule. When she had her children, it was not unusual for all new babies to wear dresses. With hindsight they are more practical, both for allowing more room for growth, and making nappy changing easier.
I'd say. 'I've never seen it spelt like that before,' and watch for her reaction. If she says something like ; 'Oh are you saying you don't like it?' I'd say 'I like the name - but people will just think it's a wrong spelling, and your daughter will always be 'correcting them.' If it was me, I'd rather be told.
