My dd (4) was quite adamant over having exclusive naming rights to the baby. We ended up telling her that babies come to their mommies in dreams to tell them their names just to deter her unwavering insistence. Her biggest naming suggestions for the boy on the way - Tyler (a name a baby cousin of hers already posesses,) Toilet (so she can poop in his mouth,) Backpack (so she can wear him to school,) Soda (so we can suck him through a straw,) Sparkle (what she calls half her stuffed toys,) Lima Bean (because she's heard me refer to him as such,) and Kitty - in deference to her same-aged cousin who thinks that's the name of choice. She asks me at regular intervals if I've had the dream yet. Even has encouraged me to go sleep to have it, lol. As I'm still stuck for a name, I'm really hoping I *do* have that dream soon, LOL.
-Only slightly relatedly, my dd already had a stuffed toy (elephant) she christened LMNO for the "They might Be Giants" song. It's a great name. For a stuffed elephant anyhow, lol.
