My two babies are 18 months apart. I love the gap. It is hard at times, like when they are both sick and dh has had to help alot but I wouldn't change it for the world. The way they love each other and interacts each other makes it all worth it. There is 4 yrs between dsd and ds and I personally have found the 18 mth gap easier than the 4 yr gap. Ds has never been jealous of dd and they play really well. There will be 15 mth gap between dd and this bb and I'm really looking forward to having them all close together. I know what you mean about the negative stuff. With each kid you have, the more you get it . The next person who says something negative to me about having 3 kids or having 3 under 3 I'm going to scream at. Good luck TTC.
