AHH!! please help me with a mamma cat issue!?

so my cat moomoo had 2 babies early this morning, and i got home home maybe 2 hours ago. im afraid that my mom and i from touching one of the babies shes neglecting it! please any advice? heres how shes neglecting it: they were happily down in my basement then about 5 o clock she only brought up one kit, not the other. she went underneath my bed with the one kit and so my mom went downstairs and brought up the other kit and put it under the bed, she didnt grab it or even try to look at it, just kept on nursing the other one that she brought up herself. do we need to do anything? is moomoo going to kill this baby? please help me and my family. thankyou so much in advance!
