My son had a fever last night & today he was ok until now he feels warm again.. don’t know what’s causing it. But cuddles and Tylenol for little man 💙 hopefully it goes down before bed or it looks like he’ll be sleeping with his dad and i again ! It’s so crammed with a full size bed with 3 people in it 🤦🏼‍♀️
