I think there are pros and cons for all age gaps. My two are just over three years apart, as I didn't want a double pushchair or two lots of nappies. It has been good in some ways, but hard in others.
I don't particularly like reins, but I have been lucky that I haven't needed them with either of mine. I can see that they have a place for some.
Had a great day yesterday and had one of those rare moments of thinking "I can do this". It wasn't anything major, just the school runs went well, both girls behaved really nicely and I managed to get lots of stuff done (cooked a meal and took it to a friend who has just had a baby, took dd2 to a soft play place and to see the baby, sorted out some of dd1's old school uniform for a friend's dd, didn't go mad when i found that dh had left ibuprofen tablets scattered on our bedroom floor, had a casserole in the slow cooker by 9.30am, had some of dd1's friends round after school for play and tea, did bedtime on my own including hair washing). Sounds pretty silly when I put it all down like that that i felt such a sense of achievement, but there it is 
Right, off to make waffles for breakfast. Anyone want some?
