My son is a happy 4 year old. I had a miscarriage a few months ago and have decided to wait a while until trying for another. The problem is, i keep looking at him and feeling guilty that he doesn't have a brother or sister. He has many cousins who all have siblings, and i often wonder whether he feels a bit left out because he's an only child. I'd like to try for another baby some time next year, but this would mean that he'd be 5 going on 6 years old. Do you think this is a big age gap? Does anyone have or know of siblings with this type of age gap, do they play together or would they grow up separately with different interests????
