I had my first child at 19, and the second 5 weeks short of my 40th, and third at the age of 42!!! Having a 20 year age gap is a constant source of amazement to people, but I slotted back into it fairly quickly. The hardest thing I find is having 2 kids so close in age, but when you see the two of them playing together it's worth it all. Funny though when some people think my eldest is my husband!!!
