Do you think a 10 month old should be left alone while a parent is working upstairs?

Well, you've got to do what you've got to do, but be prepared to alienate (at least) your brother-in-law and his wife. It sounds like he is very self centered and, I would bet, the boss in his family (strong type A personality). I don't know where it will stop, but there will be a lot of really stinky stuff floating around-and may never dissipate. A person with his personality will definitely blame you for the problems that arise. From what you have said he thinks his time is far more valuable than others and, therefore, will not understand your anger.

Rather then going to your sister in law right away and starting a fight amongst them and maybe yourself why don't you approach your brother in law first. Inform him that what he did was not only wrong but could have proved fatal or dangerous. If he listens with an open mind he will thank you for your care and concern and not repeat this action. If he tells you to mind your own business and that he'll raise his kid with his standards then you may want to let the little guys mother know of what happened. It's purely a judgment call and one that only you can make. Perhaps discuss it with your husband first and get his opinion on how you would be best to deal with this situation. Regardless best of luck to you.

yes and no

yes it's fine if you check on him/her VERY often, or (better) you have a baby monitor.

Not if you just leave him/her there alone and don't even check on him.

I think you should stay out of the mess with your sister-in law. If you think something was done the wrong way, you should go to the child's father and in the right spirit tell him why you think it was unsafe.

However, since you weren't even the one who saw the whole thing happen, I think he's prbably get mad at your other family members for gossiping about him and his mistake.

Your brother-in-law needs to be monitored, since he revealed his inability to be a responsible parent. Here is the deal. If you don't tell her and something happens, then how will you feel? Do not consider this a mess, but a situation that needs to put away. Tell her. She needs to know. Deception is not a life tool that brings peace or happiness.

I would stay out of it. But you're right. Something terrible could have happened to him! You can NOT leave a young child like that alone for any length of time. Not only could he have choked on something, someone could have come in and kidnapped him, he could have gotten into something-it could have fallen on his head, children can get into cupboards and swallow things they shouldn't, . A number of things could have happened.

However, you don't want to get in the middle of that mess. And it isn't your child, no matter how much you care for theirs. Hopefully he has realized his mistake and will never do it again. It also sounds like he needs to prioritize. But, that's just an observation...

you know you can always call DSS Anonymously if you think it is important. I would bring it up to your sister in law too. I mean i would want to know what is going on.

That is so not right to leave a baby by themselves for even 1 minute. Why can he not bring a play pen upstairs in the least ?????

Be careful about getting in the middle of family issues like that...you are right to be upset and perhaps you should find a way to let your sister-in-law know, but don't make it sound like you are tattling...

To be honest, i do no longer prefer to sound harsh or impolite yet your mum and dad easily ought to awaken ! they must be lots stricter on abode rules and that i know it particularly is an quite perplexing situtation that your in. How previous are you ? in case your purely some years off sixteen or 18 then its time to start up thinking approximately getting yet another abode. Your mum ought to no longer prefer to declare or do lots with the aid of undeniable fact that their no longer probably her teenagers even nonetheless she ought to handle them like hers. i'm rather surely asserting for now it particularly is going to be problematic yet purely handle it or talk on your mum while your on my own sometime. purely say you are able to no longer take it anymore. Spill all of it out and tell her you want a have a lock on your mattress room and bathing room ! you prefer to have so lots greater privateness and be dealt with like a grown up. attempt to sound disenchanted and if this verbal substitute will become emotional then there is easily no longer something incorrect with that, with the aid of fact your mum ought to comprehend that no longer something's going to correctly and it desires to all provide up ! i in my view do wish you talk over along with her approximately this otherwise it ought to worsen. wish it enables ! :) & good success ! Spill all of it out and DONT be Scared !

i think that is wrong to leave a child his age alone he could have died or something like that i think that you should tell her something if ya'll are close but if not and she gets very agrivated by you then just stay out of this.
