I have a 3 year old DS. I'm only just coming round to the idea of a second one - a small gap was 100% not for us at all, I couldn't have coped.
I'm now wondering if it's better to have another one before or after he starts school, which will be September 2020. I worry if he starts school and has a sibling all at once it might be a lot of change for him, especially as we'd likely be moving house around the same point. OTOH it would be nice for me to have time alone with a new baby while he's at school.
I'm 28 so I have time on my side but obviously don't take anything for granted re: getting pregnant, a healthy pregnancy etc.
