I would love to know how to pacify my almost 6 month old?🙏 so fussy and always wants me to hold her...no one else...I love how much she loves me, but my back and hips are in PAIN from holding and carrying her all the time. I work from home and also have a 4 yr old that needs my constant attention. I'm on anxiety meds so I don't lose my mind, but my back is in pain. I need something to almost entertain my LO so I can catch a break. She's so happy if she has my attention and not so pleasant if I put her in swing, rock n play and walk out of sight. I'm tired! Who else is 😴?? Haha, don't answer that last one😉
