With our parents' baby boomer generation, it's the norm to see 5/6 kid family homes from their era. My parents and ILs all have at least 4-6 siblings and so do many of their friends.

However, it's just my brother and I and DH is an only child. Most of friends only have 1 sibling, if at all, and the most I've seen is 3 kids total.

How many brothers/sisters do you have? Why do you think it affected our parents' generation and how will it affect the number of kids you have?
