There is 15 months between my 1st two, it was hard work but not as hard as everybody kept telling me it would be, luckily kirsty (my daughter) was walking before Jesse (my son) was born so that helped a lot. It was constant nappy changes etc and they are close although they fight like cat and dog at times but then again what siblings don't! When Kirsty was potty training all the running up and downstairs was hard work and it felt like as soon as i'd finished training her i was starting again with jesse but i must admit the weight soon dropped off me.
I have also got an 18 month old son (Ben) and have just got my BFP for number 4. I've always wanted 4 kids and I wanted the next two close together also but not as close as Kirsty and Jesse were. I have really enjoyed the one to one time i have had with Ben, especially with Kirsty and Jesse being at school and i missed that with Jesse cause life with two so small was just rolled into one and you keep going and so miss that one to one time.
There are good points and bad points but at the end its only a decision you and your OH can make.
some good points are...
They are generally going to be there for each other at school cause there will only be about a year or so between them depending when their birthdays are.
They can play together in the soft play places that have an age limit on them so its not a case of one can go in one cant.
you generally have a closer circle of school friends cause there is not too big an age gap.
not so much jelousy over the sibling (well i dont think so anyway)
fun fun fun
bad points
feeding, bottles, changeing bags etc is constant and ongoing
always knackered
miss one to one time
can't really think of any more lol
hope this helped, sorry it was long
