My wife stayed home with my son, so we didn’t need to get childcare- she didn’t have a high paying job nor a career, so it worked for us. It did mean going without for somethings, but we didn’t feel the need to buy stuff for him to make up missing time.
He went to a Montessori preschool (kindergarten) from about 3 years old. It matched my philosophy, in the sense of treating him like a mini adult rather than a toddler.
Primary school is a smaller (1.5-2 form years) which suited his personality.
Sports wise, a bit of swimming and some running occasionally.
We didn’t allow him to watch any screens for the 1st year, but now are a lot more relaxed.
Much like training dogs, where it’s the owner that requires the changing - I have changed a fair bit. My dad travelled a lot when I was a kid, so I didn’t see much of him when growing up - and when I did see him, he’d be drinking. So, I decided to be a positive role model - stopped drinking alcohol, regularly running/going to the gym and giving my son as much time as I can.
There isn’t much I’d change tbh - he seems content and confident in himself. Kind, shares well (this took a few years, ofc - it isn’t natural to share your favourite toy!).
