My Baby Can't Sleep And Always Wants To Play At Night

Hi mommies, I have troubling handling my 2++ month LO. Whenever she's with my mom, she can sleep on her arm and sleep quietly with her on the bed. But when I do the same thing my mom did, all my LO did was crying for attention. I have fed her alot of times, make her burp but she looks like she sees me as her playmate, being dramatic, I even carried her around, shushing her to sleep. I don't want to bother my mom alot so she can make her sleep. ? How to make her sleep? ? My arms are so tired after carrying her around...
