I'm an only child, DH has a sister who is a year and a bit older than him & a brother who is 6 years younger than him - he's closer to his brother, but was very close to his sister when they were little...
We'd like at least 3 kids, possibly 4 and we were discussing TTC within a year of having this LO - we've decided to wait and see how it goes though, because we could really have done with having a few things sorted out before this LO came along and it's only going to be harder with another one!! (We have no insurance, so we've had to pay for medical costs out of pocket, and we need to learn to manage our money a LOT better - we could afford another baby, but it would be much better to have plenty of savings put by first, so we're really fully prepared!!). I think once Evelyn is a year old, I would be much happier considering TTC again, depending on our situation (we were going to buy a house this year, but decided we needed to save up a bit more to be comfortable with it..) and frame of mind.
