In my family i have 5 siblings. there is a 11,12,14, and two 16 year age gaps between me and my siblings. I'm the oldest at 17, the two youngest are 4 and 6 months old. i get along pretty well with them but I'm more of a 2nd care taker for my moms kids, which is fine. the next oldest will be starting school this year as I start my senior year of high school. I've bonded with them all pretty well, though the bond is kind of strange because I've helped take care of 3 of them since they were born seeing as my mom is a single parent. i think that its kind of too big of an age gap unless you also have other kids who are closer in age to the oldest. my view and experience on it, thought I'd post.
