Two week old won’t latch now-Help!!!

Le

My little man is two weeks old and for the past two/three days he doesn’t seem to want to suck on my nipples. He latched so great from the minute he was born and his sucking was strong. Now when he gets on my nipple he fusses and cries and won’t suck for a minute or two and he will try and push off my boob. He does eventually latch but his sucking doesn’t seem as strong. My supply is still good. Has anyone else gone through this? Any tips? I’m terrified this will continue or worsen!!!
