2yr 8 mnths old daughter_disturbed Sleep

My daughter is 2 years and 8 months old (weight 10Kg), since her birth she has very disturbed sleep where she keeps waking and demanding to put her back to sleep by taking her in our lap and tapping her etc. It's only in morning hours she has sound sleep for 2-3 hours else the whole night she keeps waking up after every half an hour or an hour. Even in this hour of sleep she keeps moving or scratching somewhere. In the morning she wakes up fresh and remains energetic the whole day and takes a sound sleep nap of an hour or an hour and half in day time. Up Till now we thought it was a phase and will pass on but now it's affecting our health. I think she have some kind of sleep issues as I have heard and seen similar age kids who sleep. Pls help me
