One month routine!

My baby has just turned one month, she wakes up whenever also sleeps whenever she wants to. My lifestyle has changed according to my baby. I have been getting nasty comments from family members about how I should put my baby to bed at a certain hour etc!!! I think my baby is too young to be getting into a routine at the moment. It's already hard coping with her waking up every 2-3 hours for a feed. I have hardly had any sleep and people like to give me sarcastic comments!!!
