So, ugh.
We are very fortunate to have a nanny-share that fell into our laps. My friend's mom moved in with her to watch her son, and offered to watch our son as well. She has a background in childhood education, is very affordable and does an amazing job. We absolutely love her and try to make sure she knows how much we appreciate her. 
The problem is that my friend is super inconsiderate of our time. For example, over Christmas she gave us a two-day notice that they were all going to go back to visit relatives for two weeks bc flights were super cheap. I ended up having to stay at home from work to watch him, bc it was too short of notice to find a sitter. And then yesterday she casually mentions that they might go up north for six weeks this summer, but you know, they haven't really decided yet. Her mom would go with them.
I'm so incredibly annoyed and I'm not sure what to do. I would hate to lose our nanny, bc we absolutely adore her, but at the same time this can't keep happening. My friend is also pregnant with #2 right now and I'm worried about what is going to happen when the new baby comes. I try to talk about it, but she is so nonchalant about the whole thing, it drives me crazy. 
I know these are things I need to talk to her about, but I'm just so conflicted on how to handle. I need an outside perspective from someone who isn't emotionally involved.                 
                             
        
Re: Trouble in Nanny Paradise
good luck!
your nanny can work things out with her daughter if there's an issue that needs to be dealt with such as holidays. It should also be your nanny who's informing you of holidays or other availability issues, not your friend.
I think I just need to sit them down after work one day as nice as possible ask them what the plans are and see if they can give me an answer by X date.
Honestly, I'd just start looking for a new nanny now because when baby #2 comes you're probably going to get the shaft.
