I would either have someone stay at your house, or come over to check on things. Now, I may get some flack for this, but, I think once a day is fine. Is twice even nicer? Yes, but, that is alot for someone that isn't staying at your house. When I go away, I have someone come over one time a day. Now, I have a boy that needs meds twice a day. So, I am unsure if I will take just him to my mom's, or have someone come over twice...I am just not sure...Good luck!
