It is a tough decision hun. It is especially hard when you don't know what will happen - how long will TTC take, etc. And at the end of the day I think there is no right answer - different things work best for different people, and sometimes things don't go to plan and you have to make the best of it - it can work out better that way anyway.

My boys are close - 19 months. To be totally honest, two under two was really hard, especially as DS2 had colic and was very hard work at first. It was probably really hard for at least the first 12 months. But now - it's great that they are so close. They get along well, they enjoy the same things, they entertain each other a lot etc. They are best friends and I love watching that. Also, DS1 was never jealous about DS2 and I think part of that was being so young. Would I change the gap - not for anything.

If this is what you want, go for it. There are pros and cons with every gap. But if it's hard at first it will probably pay off later and vice versa. And besides, no-one else has to walk in your shoes.
