She won’t sleep , help

so my baby is currently only a week old & my mom is saying I spoiled her & now she won’t sleep without being held, it’s only been a week & honestly I only hold her when I’m feeding her or after I change her diaper maybe sometimes other times but other then that she’s in her swing & all day she’s been sleep like usual 👀 except for when it’s time to eat or a diaper change but for the past few hours she’s been only sleep for a little bit & thats only because I give her a pacifier then once I take it .. few mins later she wakes back up crying but when I put her in my arms she sleeps no problem, it’s 12 & I’m so exhausted & I have no idea what to do .. I just fed her & for some reason she only slept for a while & now she’s back up .. I just bought a co sleeper for my bed in times she doesn’t want to sleep in her bassinet but if I did spoil her I don’t want to makes things worse , tips PLEASE
