I have an appointment tomorrow so I will ask. Thank you for your response :)
Your baby could also be on a different sleep pattern than you. His awake time may be while you're sleeping and he isn't big enough to really bother you right now. Walking and moving can lull him to sleep. If you're ever concerned try eating or drinking something cold and lie down for a while to see if that gets him moving.
My baby also has weird patterns of movement. She will have slow days to but there is always movement. It when you see a continual decrease in movement you should go to the doc. continual meaning less and less. Babys do sleep so they will have moments where they are quite. My Ob Has me doing kick counts each night to keep track of healthy fetal movement. Maybe you can ask your ob about this. Dont worry! im sure your baby is fine since he is moving! :)
Some babies just have irregular patterns of sleep. As long as he is still moving, he should be fine.
