3month old sleeping all day?


my 3month old daughter has been sleeping what seems like all day here recently. Today we woke up at 6am to feed and went right sleep. Then we woke up around 10am and went back to sleep around noon and slept till 2pm. she now went back to sleep at 4pm and has been asleep since and it's 6:30ish. she won't go to sleep till around midnight. is this normal? she started to stay up longer but now it feels like she's taking a nap every 2 hours again.
