I need tips please.

My daughter will be four months old on the 16th. We are very blessed that she sleeps GREAT at night. I put her to bed at 9-10pm and she wakes up anywhere between 6:30-8am. But shouldn't she sleep a little during the day too? She fights me so bad. I make sure she's fed, changed, not to hot or cold. She'll just cry while I rock her and sing to her. I don't know what to do. I need tips please. I'm sorry if this is dumb to ask.
