I have 3 children. Eldest is autistic and can be challenging middle has adhd but manageable at the moment, youngest (2) is very easy going and been a dream and perfect for our family really helped calm the older 2 down. We're now debating a 4th but worried how it would work. 0-1 I found easy 1-2 I found hard and 2-3 I found easy.
so asking for any experience of going from 3 to 4 children
