@Thesnakeminder, I’m not going to get into an argument with you, but these type of questions are usually posed by those who have never experienced having ‘absolutely no childcare’.
I had no childcare, I was a SAHM, husband worked very long hours, no family at all nearby, friends all working, we were not from the locality.
In relation to an emergency appendectomy, my DH would’ve looked after the children, but, I’d have been in hospital, having surgery and then being cared for in hospital.
As to scans, given that the baby has 2 parents, it’s nice for the father to go to the scan, both just to be involved and potentially for support.
I have had 4 scans where I’ve been told the baby has stopped developing, 3 of those I attended alone. It wasn’t fun.
I then had another baby in 2020. Lockdown meant my husband attended no scans and nearly missed the birth. It took a few weeks for me to even feel like he was involved as I’d done it all by myself (not through any fault of his by the way).
Also, when you have ‘absolutely no childcare’, finding it is hard work. It’s much easier to get that help in an emergency situation than for what is perceived to be routine appointments. So no, it’s not the same.
