DD has 2 night feeds (3am and 6am) if she goes to bed at 11pm or 3 feeds (1am, 3am, 6am) if around 10pm. If she is peaceful I happily have a late bed time, but if she starts to get retless we take her to bedroom earlier. I don't mind her night feeds as they are shirt (10 mins) "down to business" ones with immediate falling back asleep again.
I don't think you can do much about it Utopian, that's how it works with 2nd child.... Don't know how mums feel about it, but we have 7 years difference with DS. She was tasked to play with me, but as a kid would tell me that when she was little mum would play with her (in particular, she has been drawing outfits for the paper dolls with DS). I was upset she would not play with me as we used to argue quite often with the sister. I even asked mum to play with me, but she did shy away from it with excuse that DS was better at playing. At the moment with 1 kid only I would love to think I would try my best to give all the same attention I gave to DD1, but reality would definitely be different... :(
