DS1 and DS2 are 18 months and 4 days apart. Its hard work at times but I love seeing them play together (when not fighting).

There is 2 years 7 months between me and 1 of my brothers and just 2 months short of 10 years between my other brother and I.

I don't think their is any right or wrong gap its what works for you and also what fate deals you, when TTC DS2 I never imagined getting preg straight away after TTC DS1 for 12 months. All gaps have pros and cons.

Good luck
