I’m sad that you don’t think spending time at home, going to the park, playing with their toys at home, baking, seeing friends, playgroups, music classes, time in the garden, on their bike or scooter, or to just play freely in their own space is not a good thing for children. Nursery is a good place for kids yes, but it doesn’t replace the benefits of being with you and your partner spending time together. Kids need downtime, nursery is a long day of sharing adult attention all day. If two babies are crying and the 3 staff members are already changing nappies/putting a baby down for a nap/settling another/giving a baby a bottle or whatever, then that means there isn’t always an adult to pick them up and offer comfort. It’s not abuse, it’s the limits of 3 adults caring for 9 babies!
You mention doctors having this level of childcare a lot - I worked as a nanny for 2 doctors when I was younger. Their hours were long and it was difficult for them to leave on time because surgery may run over or emergencies happen. So they had in home childcare, because they knew 40-60h a week in childcare wouldn’t be sufficient for their work hours for 2 kids. The mum went back to work part time after her second, she took Fridays off which had a salary impact but it meant she spent time with the kids at home just doing normal things. Yes a career is important but I think people are imploring you to consider (from their place of being a few years down the road) that this time vanishes so fast and absolutely no one has ever said ‘I wish I had worked more and seen my children less’.
I hope you find whatever you’re looking for, I honestly would consider working even one day less a week (and perhaps your partner too, or even a half day) because the schedule you’re proposing is a lot for all of you and especially a very young baby.
