I try not to judge. I don't see a problem with a SAHP having their child in daycare for 1-2 days a week. Any more than that though and I probably would silently judge TBH. If you're able to be at home then why not spend it with your child rather than paying others to raise your child for you? There are also limited spots in daycare in a lot of areas, so it's not really fair on those who actually NEED those spots. I understand that there are exceptions - I know of someone with mental health issues who had her child in daycare 5 days, although she didn't work, as she was aware that she wasn't really capable of raising her child full-time. I can understand in those kind of circumstances, and in her case daycare was needed just as much for her child as it is for children of working parents.
Each to their own though.
