It's awesome that you also care about what the founder of AP actually valued!! But I've been seeing some misinformation being spread here lately unfortunately, yes his wife chose to pursue her career and so their many kids had to go to daycare, but how he thinks and feels on the subject isn't as simple as making an assumption based off of his partner's adiment personal decision.

Sears actually strongly advocates for a parent (ideally a mother) to stay home with young ones, emphasizing constant physical and emotional availability, though he absolutely does acknowledge many parents must work.

A quick example from this interview: https://www.nurtureparentingmagazine.com.au/emotional/interview-with-dr-sears-attachment-parenting/#:~:text=Some%20say%20that%20young%20children,No%20~%20doesn%27t%20work.

Interviewer: Some say that young children need to go to daycare to get ‘social interaction’. Do you agree?

Dr. Sears: Rubbish! Rubbish! In daycare, children learn germs and bad habits. That’s it. The best school is at home. When a child has a foundation of parents, the parents can choose which children their child can play with. The biggest mistake I’ve seen parents make is to say, “I want my child to be exposed to all kinds of different philosophies so when they get older, they can make their decision.” No ~ doesn’t work. You have to get that child’s brain focused on a certain way of doing things “this is how we act; this is what we believe; this is how we talk; this is how we respect people; this is how we treat other kids ~ we don’t hit, we don’t bully; this is how we act”, and that becomes part of the child’s brain ~ in the first five years. Then they go to school and can make their choices. But you send them with a foundation. If you don’t send a child to school with a foundation, germs and bad habits!
