Superstitious and In Law Buying ?

My bf’s mother surprised us with a couple gifts when we came home today . She went out and bought a baby blanket and a 5pk of bodysuits all white , im only 8wks 5 days and dont feel comfy accepting anything from anyone just because I have that pregnancy “ nervousness “ if thats even a thing . Idk what to do

Give back and tell her dont buy until I know the gender , keep and not say anything ??? Idk what to do its just me .
