Posting in AIBU for voting.
DH and I discussing, it came up in conversation with family - we can see pros and cons to both sides so we're sat on the fence.
If you had 1 DC and financially could afford to send them to private school but you couldn't afford to send 2 x DC to private school - would you say it would be better to stick at one DC?
Taking into consideration that the catchment state school in your area is OK but not brilliant.
Yabu - it's more important to have a sibling than a private education
Yanbu - stick with one DC and give them the best education you can
