check for teething.. it's in due time for him. check for bloating.. rub some ointment on the stomach n back check anything that might make him uncomfortable..is it only at home or outdoor too? . . . sing him some nice lulabye or prayer to sleep.
Hi, maybe you can check on his stomach. Maybe he's experiencing colic. To make him calm before sleep, you may open any white noise or lullabies to drive him sleepy.
