Thank you for all of your suggestions. You are really good at coming up with ideas. You see my first instinct for a girls name was also Florence. I really like it. And i think it 'goes' (and also with DS's name which is easier to find things to 'go with'). I realise that they wont always be called in a 'three' and so that names dont have to be matchy matchy but I would like them to have the same feel about them I think.
Of the boys I like Henry/Harry, George, William, Freddie but a bit worried about the similar name ending in 'ee' sound. There are also loads of George and Harrys about at the moment. Maybe I am overthinking this!
Of course DH will also get a say but at the moment he cannot come up with anything AT ALL. Baby naming is so hard, thankfully this will be the last time we do this
