I wouldnt even think twice about it...you chose to stay home and work for the betterment of your family...if ANY of them needed you you would be there for them no matter the time of day. Yous kids and hubby come first and foremost and that is what you did, nothing wrong with your choice. When someone chooses to go with am in home daycare provider they know they are chooseing to go with someone who has put their family first, thats why they do what they do, and not only that but they also know you are the ONLY one to do your job, therefor they should have someone as "backup" for these specific situations. there was NOTHING you could do, you made the right choice to not only, be there for your son but also to keep the daycare away for their "health". Nothing to worry about. Maybe if you havent already, now would be a good time to inform ALL parents of the need for "last minute" back up care, in the event you are not available to take their child. FAMILY FIRST! thats what I always tell my dc parents. no apologies!
