We had #2 when DS was 4 and I love this age gap, he is independant enough so that we can have individual time with both of them. He went to pre-prep when Ari was born so I had a couple of days a week where it was just the two of us and DS is great friends with his little sister they have barrels of fun together and he loves helping out with Ari.

Having two does take slightly more organisation but on the other hand they keep each other amused :-)
