Ooh I put a 'last baby' bling request in recently too! But I would like one which has the birthstones of DH, DS, and baby on it. Diamonds would actually be optional, I would like it eternity-style though. DH is October (opal), DS is August (peridot) and baby could be August but if September that would be sapphire.
I went to the supermarket today with my mum to get things for DS's cake, and it was exhausting. However I made a lovely discovery. DH and I use an app on Android called 'our groceries' because either of you just add things to your shopping list and it synchronises up in 'the cloud', and whoever is shopping can get them. You can have multiple lists e.g. an ikea list, a supermarket list, a birthday list. He's made one called 'birth stuff' and (I know how MN loves a shopping list...!) it already has had crossed off it 'bubbly', it's got "birth plan", "birth pool", "biscuits for midwife", "candles", "clear table for baby and midwife admin", "heater to warm a cold baby", "old sofa cover", "phone number list (emergencies)", "[Rake]'s favourite food", "sushi", "spotlight", "Warm towels", "water thermometer", "waterproofing (cheap shower curtains)".
He was obviously listening very carefully when the MWs did their pre HB home visit
