8 month old DS's new nanny started last week, and I have been working from home in order to show her the ropes. DS is a big boy, and has always wanted a good amount of daytime sleep, which luckily for us paves the way for good night time sleep too. But despite her assurances that she wants to continue DS's routine (he is a very routine-y baby, with predictable nap times during the day) whenever I have left her alone with DS, she has given him a shorter nap in the morning than he can cope with. The result is that he is generally more irritable, sleeps badly during his lunchtime nap, and is really cranky in the afternoons. I think his night time sleep is being affected too (waking up at 4.30am one night, for example, which he hasn't done since he was 3 months old). For the last few weeks she's just been coming in in the morning, so hasn't seen the consequences of shortening his nap, but it's really irritating me that she's unwilling to give him the morning sleep that he needs! Would it be out of order for me to say something AGAIN to her (I've tried not to labour the point up til now, just mentioning that what DS likes is an hour's nap in the morning, let's not change it as it's working for us at the moment etc etc). Or, for the sake of establishing a good relationship with her, do I bite my tongue and let DS continue to be under-slept??? Has anyone had to have a similar conversation with a new nanny, and how did you go about it? Subtlety isn't working for me at the moment.
