I've had two infants multiple times over the years. Currently I have a 6 year old, two 4 year olds, two 2 year olds, two 1 year olds and a 5 month old. Next baby was born last week and will start in August.
Multiple infants can be a challenge at times and can disrupt the routine of everyone, but its just something we all get used to
I enjoy infants as they tend to stay with me until they head off to school
