Kids close together (3 under 4)

Lauren • Girl mom x3 ❤️

So I have a 20 month age gap between my daughters and we are planning on having a similar gap again.

The reason being is there is 9 years between my stepson and my girls and they barely interact with each other at all. We've decided to have our children closer together to encourage a closer bond.

What are people experiences with having 3 under 4?
