Looking for some advice. Finally got my husband on board with baby no#3. Currently have 5yo and 2 (almost 3)yo. Littlest starts school in 2023. Ideally (aware things dont always go to plan) baby no3 would arrive summer 2023 (littlest starts school in Aug). For any experienced parent....is baby best arriving good few months before/after starting school, or doesnt it matter? Dont want to unsettle him at a tricky time in starting school. Advice greatly appreciated.
