Attention

My children 9, 7, 5, and 3 seem to be disengaged when I am giving basic instruction (sit at the table, come for dinner, go brush your teeth, etc.). I don’t want to feel like I am just giving orders all day and am feeling frustrated. I feel like I am missing connection but also frustrated because it seems that they are ignoring me. Could you please give me guidance on what to expect and how to better communicate instructions or instill better habits? Feeling tuned out.
