My daughter sleep in the same room of my helper. Not much problem because my daughter still likes me the most. I spent just about all my after hours with her (she is now 13 months). It is far too tiring to wake up so many times at nights even she has cut out night time milk. I need to work during day time and I have only tried one night when I started back to work and no thank you. I am just a human. You can try to buy a folded bed (I brought mine in Priceright) and put it under the baby bed during day time and take it out at night. My daughter wakes up a lot of times at night and sometime she wakes up very early, around 6am. It is really hash if you have to take care of her at night as well as going to work during day time and fool around with her after work. My helper can sleep during daytime if she is very tiring at night. I also switch on the air con. in both bedrooms last summer and the electricity cost was trible but I have no choice.
