Can we eat normal during confinement

i think is up to u whether u believe the old ppl saying. bcoz u will only see the effect much later, like when old? for me i followed quite strictly, just confinement food, red date tea and plain water. i did the confinement aft stillbirth which i conceived via ivf (3rd try). just aft 3 mths i conceived naturally, really surprised. so i not sure issit bcoz i did a pretty good confinement which boosted my body. so i will continue to do the same confinement routine for my 2nd pregnancy
