I was five when my brother was born, and had to change his diaper (with safety pins) often.
I was going to use cloth diapers with my son to save money, was even given a bunch. However, he was a preemie, and when we brought him home all the diaper covers were too big around his legs and the diapers just leaked everywhere. Then-husband went and bought disposables, and by the time my son was big enough to use the cloth diapers without issues, we were spoiled and stayed with disposables. It helped that we'd get big Costco boxes of diapers for birthday and Christmas presents!
