After feedings, I keep him elevated for about 15 mins. Then afterwards lay him on his belly elevated on the boppy. He'd wake up chocking that's why I would lay him on his belly. Or even his side if that's too sketchy for you. I honestly think the gripe water makes it worse for him, after I stop using it he wasn't all colicky as much. Oh we also try to get two burps in. One in the middle of feeding and one afterwards. Hope one of these work for you !
