I suggest that newborns buy clothes, split.
First of all, from the point of view of warmth, in the case of the same material, the warmth of one-piece clothes is not as good as that of split clothes. Newborns' legs and feet like activities, and conjoined legs are easily exposed, resulting in different temperatures felt by calves and upper bodies.
Secondly, in terms of baby comfort. Split clothes hardly restrict the baby's activities, while conjoined clothes will show its limitations when the baby stretches.
Secondly, if the baby's lower body clothes are accidentally dirty. For conjoined clothes, you can only take off your whole body and change. But for split clothes, you only need to change the pants of the lower body, and you don't need to change the autumn clothes of the upper body. Just don't be too friendly.
Finally, at the end of the day, eating and drinking Lazar is the most important thing. As a battle-hardened old mother, it is more convenient to change clothes by repeatedly defecating and urinating with diapers. Siam, you need the baby to cooperate. And sticking out from both sides of the baby's stomach to stick the diaper together.
Tips, split clothes under the same fabric are much more favorable than one-piece clothes.
