My LO is coming to 4 months. He is able to sleep for stretches of 4-6 hours at night.

However, my wife tells me that I should wake him up at 4hour for feeds nightly. She fear that he will develop gastric. Do I have to feed him every 4 hours or to let him sleep and only wake up when he is hungry. #pleasehelp #advicepls #firstbaby
