fasting with kids 😤😤😤

Mr
So it's my oldest girls first time fasting 12 and 10... it's only 12:43 pm and my 10 yr old done asked me 20 times what time is dinner... my husband was a little easier on them he let them eat until 10 minutes before sunrise which is at 6:01 am... 
How do you ladies deal with the whining and nagging of fasting kids..Â
