My 3 day old ap- started Monday- has been out for 'walks' every night for the past 3 nights for 3-5 hrs/time. We required some babysitting last night and the second we were home- she was out the door. I know when she returns as I can hear her (she does attempt to be quiet). She's older 27, and has a bf in the area and some friends. Its Shoreditch so major party area. So far hasn't affected her work. Today, when I mentioned another babysitting on Fri- she actually said 'not a problem, just let me know what time you'll be back so that I can plan with my friends' to which I responded that for our family, the whole idea of having someone living with us is the freedom of having time to do what we need to do and that she should just assume that babysitting nights to be off-limits and a bonus if we're back early. It did piss me off though. She's the second aupair after 2 months after 1st one decided kids are not 'her'. Prior to this, we had an older homehelp/nanny who lived with us for almost 4 years, so we are not exactly new to this.
Should I worry? I expect this to be the pattern. What to say at her 2 week review?
