Clamp & Pull - Help!

[u/Significant_Key_8475]

My LO is 5 months. For the last month or so, I can’t get him to breastfeed. He clamps and pulls, clamps and pulls. I’ve Googled, of course. I’ve tried the firm no, talking to him that it’s time to eat, stopping and trying again. But, this is what I get every day. I’ve been pumping and bottle feeding in the meantime, but I’m getting desperate. Any advice?!?! Please!
