I remember myself as a student every first day of school. I would wake up in the morning for the first few days with butterflies in my stomach. The duration lessened as I went into college. But I was always anxious. Today is my eldest's first day, but he didn't have to go through the same anxiety I had. For him, it's just another day at home with loved ones. It was me, who had a little anxiety last night. Of course, I was wishing it would be the perfect 1st homeschool day. So I limited ourselves to just letter practice, counting with Math U See, music, and story time. But we did take the whole morning because it wasn't as different from his usual day either in the sense that I had to ask him several times to finish the task. But as I was doing so, I would repeatedly tell myself that it's really about training him for things such as obedience, diligence, and attentiveness.
And so it went okay. We're a little off with the schedule, but basically, we stuck with the lesson plan. I just have to remind myself everyday, otherwise put up a DIY poster, about building, and not breaking my child, and to have the attitude that would encourage him to develop a love of learning, and not a homeschool burn out, and of course, to prioritize on lessons that will make him become a better human, and not a walking encyclopedia.
Keep it gentle & loving. Here's to a smooth sailing... cheers!
