I've been FT, PT and SAHM since having children. They all have benefits and pitfalls.
Being a SAHM works for us as a family. DS1 has sensory issues and some SENs and finds a school day much tougher than his 10 hour nursery days. He usually emerges from school ready to blow and needs quiet 1:1 time for a while to defuse. Full time wrap-around care in a cramped, mixed age room was awful for him.
Life was manic. DH pulls his weight, but when he's away which can be short notice, I had to do everything solo. Co-ordinating joined-up parenting is another layer of mental load. I was on the go 17-18 hours per day between planning/ marking, dealing with children, formal work hours, squeezing in pick-up, a few hours of family life then resuming planning and marking when the DCs were in bed.
As a SAHM, I seem to have found plenty of other ways to keep a certain level of chaos and urgency in life
I don't enjoy the domestic burden and it does dent your connection with the world and sense of worth. The personal time is great though.
Part-time was generally good but there is more than your fair share of work as some areas of expectation don't go down with hours and salary. Teaching 3 days a week still averaged out as full-time hours compared to a 9-5 role, plus there is more domestic load.
Different balances suit different individuals and families. SAHM to school age children definitely beats babies/ toddlers (I remember the relief of dressing in nice clothes and being alone in my car looking forwards to herding reluctant teenagers
). Assuming no substantial changes to life, I can't see me voluntarily seeking work until the DCs no longer need wrap around care. Fortunately in my field, supply work is a fairly easy entry route back in, plus I've kept up relevant voluntary work.
