I have a 46 month daughter and I am 36 weeks pregnant!!! Help me.?

I have a 46 month old daughter and I am 36 weeks pregnant. My daughter still takes a sippy cup to bed with her. She makes me mad sometimes because she wakes up several times a night for her "SIPPY". How can I brake her without being to mean. She is very spoiled and bratty. "I SWEAR, NOT MY FAULT" I just need some hints on how to handle her and the baby after I have my c- section. I have no source of help at all... Please be open with me!!! Thanks.
