Plan the unlock
Keep the exact condition — Reach your child's first birthday. — as the completion target. Open heart events and relationships for the relevant system, then check Steam’s own achievement state after completing the action. Your local tracker checkbox does not trigger the Steam unlock.
If it has not unlocked
Time Flies was explicitly fixed in v1.0.5. Confirm the installed version before following an older workaround. The official note does not specify a universal retroactive-unlock procedure; do not delete or overwrite your save to force it.
Save your checklist
Mark the achievement in the browser tracker after checking Steam. Export companion progress if you want to move that checklist to another browser. No account or game-save upload is required.
Sources and version context
Steam 1.0 conditions; v1.0.5 fixes reviewed. Dataset checks are separate from the current game version; a patch review does not claim that every granular value was retested in-game.
