Normal ba?

Yes its normal, just imagine it this way, during the day when you do most of the work, chores, walking, aside sa busy ka, its like parang na hehele mo na si baby, while at night, when nakahiga ka lang, the baby tends to move more kasi parang hindi na sya hinehele :) Also, your baby’s brain is maturing as time goes by hence more defined movement which is a agood sign.
