There's 3 years between my sister and I, and at times it seemed huge. Now that we're both older and are mums its OK.
6 years from me to my brother (very big), and then another 2 years to my other brother.
My brothers are really close.

There's going to be 19 months between DD and Beez, if all goes to plan. Scary thought, but I know I can handle it.
