I know this sounds very broad but would you share an insight to your home life (maybe was before the lockdown)?
I dont personally know any household with 2 full time working parents. Every family, including my own sisters, has one partner who doesnt work or part time or fortunately in a more flexible/local type job (GP, teacher, freelancer).
My youngest starts primary school this September and DH works slightly longer hours than I do, no family so have always relied on paid childcare. I found babies and toddlerhood a relative breeze to manage.
