My sister and I are Irish twins (we are 1 year and 4 days apart) and we fought like cats and dogs when we were little-we're talking knock down, drag out, cat scratching, hideous shrieking fights.  We get along pretty well as adults, but it was BAD as kids.

I always just assumed that it was because we were so close in age, so we decided to spread our kids out more.  Monkey is nearly 4 years older than Baby Bug and they get along swimmingly!  They play and laugh and have a great time.  Of course, when I got pregnant so fast after we had Baby Bug, I was really worried about her and The Bean, since they are just under 15 months apart, but they seem to be getting along great as well.  And of course Monkey is gaga over the baby.

My question is, do you think I have something to worry about in the future?  How do I help the girls not scratch eachother's eyes out...if they feel so inclined?
