paranoid!!

Every little thing makes me so scared that something is wrong with my little man! He got a small red patch in his leg, so I showed my mum and said it's just where he's sweating. Then I thought he's had thrush in his groin and mouth because I'm on antibiotics, but on calming down there's nothing there! I feel like I'm failing and he's going to get sick! Google is not my friend! Anyone else struggling with being rational?!
