I think you need to communicate with your CL if she is okay with this sleeping arrangement. If she is okay, then it should not be a problem.
There are some CLs who mind. So do communicate clearly with them first.
Also most importantly, I learnt that we need to set our expectations of the CL right at the start, so that she knows what we want her to do and follow.
Actually I prefer my original CL. She is more on task and she is fast. The replacement CL is also a nice lady. Just that I find her quite slow motion type. Both of them have different styles so I am still trying to adjust to the replacement CL's style. I'm hiring this replacement CL for 2 months because my mum had wanted it with the original CL but she can't do 2 months as she has another confinement case after mine. But who knows she falls sick first before she completes her assignment.
I personally also find this replacement CL not so particular with cleanliness. Just now I saw her wash my breast pump and put it in a container. There is some leftover water in the container. After putting my breast pump into the steriliser, she poured the leftover water into the water tray of the steriliser. I don't know. I find the leftover water dirty leh.
