Oh so sorry. My worst moment was navigating a badly designed parking garage with a steep slope. Toddler runs off into traffic (never done it before or since) and I go to grab him, let go of the stroller for a minute, and stroller SPEEDS AWAY DOWN THE PARKING GARAGE INCLINE and hits our parked car hard enough to dent it. Baby was strapped in to the car seat which was attached to the stroller base. I can't even imagine what would have happen if she wasn't strapped in or it had been the regular stroller base. And I never use the car seat attachment with her. It took 30 minutes to separate the stroller/car seat from our car. (And thankfully, it hit ours).
And two days ago, toddler pusher her and she slid under the water in the bath. Stared at me surprised, breathing in water. I grabbed her immediately but she still ingested a ton of water. What if I hadn't been there?
