Generally, baby jumpsuits have hidden buttons on the shoulders and crotch. The specific wearing method is as follows: unbutton the hidden buttons, then roll up the jumpsuit, put it on the baby's head, and lay the baby flat on the bed. The mother grabbed the baby's leg with one hand, spread out the clothes with the other hand, put one leg of the baby into the trouser leg of the jumpsuit, and then put the other leg in the same way. After putting it away, straighten the trouser legs. Then put the baby's arm in the sleeve, and so does the other arm. Finally, pull up the baby's jumpsuit and button it.
And a jumpsuit without a head. Usually tie or button. First, unbutton all the buttons or ties of the jumpsuit, and then put on the jumpsuit for the baby, with the neck aligned with the collar. First put the baby's legs in, one leg at a time, then spread the sleeves by hand and put the baby's arms in. It's best to pull the baby's clothes, button them or tie a belt.
