Do baby pants have a large crotch opening on the front or a small crotch opening on the front?

Small crotch
The crotch design of baby pants should be that the small crotch (smaller opening) faces forward and the large crotch (larger opening) faces backward. 12

This design makes the baby more comfortable to wear and also avoids the inconvenience or discomfort caused by improper opening of the pants when the baby is moving. It is very important to consider the baby's comfort and convenience when designing and selecting baby clothes.
