Hmmm hard to recall, but I have memories of them sitting on the kitchen counter yet so they could see me, so maybe 1? Mixing baking ingredients was before hot stovetop cooking but they watched. We spent a bit of time sailing when we had our first son, and I can still see him sitting in his car seat in the galley watching me. His favourite easy boat food was garlic and black bean couscous instant cups. He still has wild tastebuds!
