I don't think there is ever a right time to have another baby. If everyone waited until they were ready nobody would have kids. I wanted another one when our dd was 3 but dh wasn't very keen on the idea at the time.
I'm now due in May and my dd will be 6 and a half when baby arrives. Sometimes I worry that is too big an age gap and I wish I had insisted on having another one when dd was still little so that their ages would be closer, but then there is the positive things like dd is at school and has her own friends, outside interests, isn't as dependant on us as she was etc. Of course there are days when I worry that another baby is going upset our happy little family but I know that in the end it will all work out fine, I hope anyway
When you start wanting one. And I hate to be doomy and gloomy but best laid plans and all that - sometimes things don't work out as you hope so you may as well just go for it.
I had my gap all sorted in my head - started ttc when ds1 was 2, new sibling was to arrive just before he was three. Two years later I finally got pregnant, only to miscarry Took another 6 months before I conceived again. So my nice neat three year gap turned into five. You'll make it work whatever the age gap - I don't think it's wise to think you can plan too rigidly.
That's what i worry about Linnet. It's all so perfact at the moment and i'm scared it will all be bedlam(SP) and that i'll not get as much snuggly time with dd!
(but i had my freind over today with her 4 month old son and am still broody)
Do you have just one child right now fairydust?
