I'll send my kids to spend the night at your parent's house...lol
We have no grandparents that would even consider a sleep over...I asked for 2 nights so we could celebrate our wedding anniversary...got no where...asked for just one...they said they'd get back to me...I am still waiting and that was two anniversary's ago.
We both got the flu once and were so sick we couldn't get out of bed...my husband and I were crawling to the bathroom...my brother and SIL drove in from out of town to pick up our kids and kept them for three days...my dad and step-mom are 10 minutes away. They were "scared they would get sick too" both kids had flu shots...my DH and I had forgotten ours.
Please send her and let her have a good time or not...she will be fine.
Oh, growing up I spend every Friday night at my grandparent's house...I LOVED it!! Cinnamon toast for breakfast every Sat...good memories!!
