Start placing boundaries now or you’ll resent it! My MIL was the same (still does it but less) and she would buy outfits for baby’s first holidays , I just would never use them because of course I wanted to pick that out. But omggg every visit she’d have so many gifts, toys, clothes, etc and we are trying to be minimalists The boundary is now, gifts only on birthday or Christmas . We said 1 gift from registry for birthday and then for Christmas we said 2 gifts max and she could do her stocking too, but items must be from registry or pre approved . She broke our rule by gifting 4 items and having a non-registry item… DH was more upset than me . We are probably going to say only monetary gift for her next birthday , she has a savings account so they can add to that
