Just curious

I'm wondering how common this is with everyone's babies. This is my 2nd child and it's the same exact thing as with my 1st. I have to be constantly walking around, not standing still or sitting with her or she will fuss,cry,& scream. She's almost 4 months & doesn't entertain herself or play with toys yet. Hates her playmat and music. Hates any baby carrier so I can't wear her. Doesn't take a pacifier just like my 1st. It is SO exhausting and I get tired and sore from walking her around the house all day. I can catch tiny breaks if I rattle a ball above her head while laying down on the bed together but that's it. She gets bored fairly quickly & tired of laying down. I've tried a sit me up chair but she hates that too. I've tried sitting her up on my lap but she doesn't tolerate that anymore. My lower back kills me. I CAN'T WAIT till she's mobile on her own and playing with toys!!! I can't stand this stage. She hates tummy time too. Will just lay and scream. She is by far my most difficult baby. My 1st atleast entertained himself in the bouncer and swing. She hates both. I have to walk her all hours she's awake. It's the only way she's content. Please tell me I'm not alone😫
