My husband's grandmother passed away and her memorial service and family gathering is the 8th and 9th. About 4 hours away from us so we will be staying overnight. Is a 24-30 hour period of alone time ok at this age? If it's not then I'll be sure to have someone come over. I'm just not sure if that's an acceptable time frame or not. I check on them probably 10 times a day or more when we're home so I'm having a little bit of anxiety about leaving them for this long.
