8wks doesn't sleep during the day

Not sure if this is ok or not, but my LO is 8 weeks and does not sleep during the day. If she does it's for 15-30 min. We've tried changing beds, putting different music on, letting her fall asleep in our arms, putting her down while drowsy. No matter what we do she doesn't fall asleep. But if we're driving or I take her for a walk in the stroller then she sleeps the length of the trip, once I stop she wakes up. Is this normal, any suggestions on what else I can I can try?  It's not bothering me too much since she is able to sleep for most of the night 6-7 hours, which I'm loving!
