I have a 1 year old & babysit a 2 year old (14 months apart) & it's a great gap - now. The first 6 months were hard. But once DS was more mobile (probably around 8 months, when he started crawling), the two kids got along well. Now they play together really well - I actually get more done when I have the two kids because I don't have to entertain DS all day. I generally get them to sleep at the same time in the afternoon - but not always. It's lovely to see Simone (the 2yo) looking after my DS - giving him toys, sharing, etc.
