The figure was indeed a bit hefty for some ordinary families, and some could only afford to buy regular formula for their babies, which wasn't as expensive but still cost at least a hundred. Any cheaper, and they really wouldn't dare to feed it to their children!
Some mothers who were in their postpartum confinement still hoped to breastfeed their babies, using formula only as a supplement, which also helped to save a bit on expenses!
Diapers, although not as costly as formula, got used up very fast. Each pack had about 50 pieces, and with two little ones like brother and sister, each would use at least five or six a day, so a pack wouldn't even last a week.
As the babies grew past their first month, they would continue to grow, and by that time, they would need larger diapers!
So just to be safe, he didn't buy too many medium-sized ones.
