as a licensed child care provider, i find this situation appalling.
first of all, it is difficult when you are put in the position of working for friends. it gets messy because no one wants to offend anyone else, for fear it will harm your friendship. however, after reading this situation, i feel you must make a choice. you can either be friends with them or be their babysitter. it doesnt sound like being both works for this family.
i would like to encourage you to become a licensed child care provider. you can contact your county's health and human services department for more information. mostly this will help because you can have a contract that is legally binding which will be clear that when the child is in your home, they are paying for the time, whether dad is there or not. if they are in your home, they are on the clock.
the reasons the child acts this way is obvious; parents let him get away with it. right? and nothing gets said when the most obvious rudeness is happeneing (swearing and rude talk to you)...it is like they expect you to watch their kid and dad too. it is rude, inconsiderate, and i feel you are being used. are you sure that they are worth the effort? friends wouldnt do things like this to friends.
i DO NOT think it is hormones, i completely feel you are being treated unfairly. YOUR HOME is NOT THEIR HOME, and once you have your baby, things will only be worse if they are coming over every day and getting in your hair. you should stop this now before it hurts the health of you and your unborn baby!
if nothing else, lock the door and stop answering their calls. they have no right to put you through this, and you dont really have any legal rights to make them pay you. if you become a licensed (or even a legal non licensed) day care provider, the parents can apply for county aid, and the county would pay you for the child's care! it isnt much (my county pays 2.43 for ages 1 and up 2.69 for 6 weeks to one year) but it would certainly help. and it might help you define the line of when and how the parents hang around in your home.
i cant believe they would think that they can come in your home and treat you this way. im just appalled and angry that this is happening to you.
so, like i said, you have every right to charge them, but there really is no legal contract binding them to pay you. i do not think that the dad is being fair to you most of all, its not moms fault, she is working, but either dad takes the kid on his own, or dont come to your house. lock the door and dont answer it! LOL.
again, you are NOT being hormonal, this is rude, disrespectful, and they are using you. its not fair and you have every right to say so. does their friendship mean a lot to you? it doesnt sound like your friendship means anything to them.
i hope, as a 3rd unrelated party, this helps you. i feel so aweful that anyone has to deal with a situation like this. it is so terrible. i dont know that i would watch the kid even if dad isnt there. he probably would act worse because he knows dad allows it to happen.
