@umaid We have driven to Port Charlotte, FL from north of Toronto multiple time with my kids. The first time my oldest was 5 months, then again a year later. We plan to drive down again this winter with a 3 month old, 2.5 year old & 4 year old. I’m more worried about the older kids than the baby to be honest. We plan the drive to be when they are mostly sleeping.
Day 1: leave after dinner and drive to border, stay in hotel.
Day 2: drive all day (approx 5am until dinner) stopping every ~3hrs
Day 3: leave early morning and arrive around lunch
You just have to have a relaxed mindset/not be rushed and it’s totally doable. Children in Ontario are in a car seat/booster until they’re around 10 now depending on height and weight so limiting trips to a few hours isn’t really realistic in my opinion.
However, if you don’t want to go or you don’t feel comfortable then tell your husband. You don’t need scientific facts to back up your feelings.
