6 weeks pp

Jackie • 24 y/o Jake G 💍 mama to LNG 4/21/17 👶💙. SAHM . Idgaf about your opinion. It doesn't phase me🙌I say whats on my mind. Gtfo my page if your a hater. I don't need that type of drama. Stay blessed . 🙏🏻
So I am 6 weeks pp and everytime I am washing dishes, taking a shower or even using the bathroom I hear baby cries. As soon as I get out of the shower or bathroom or stop washing dishes the sound goes away.. I ask my hubby is baby crying while I'm in the shower and he replies: "no?" And gives me this look like I'm a crazy ass hearing things. Even when hubby isn't home and I'm alone with baby sound asleep I hear it each of the times I listed above. 
Anyone experience this? Or know why this happens or is it just me going crazy. ?
