You can choose thermal underwear or a cotton skin-friendly garment outside the baby's down jacket liner, so that the baby will be warm, and you can also wear some loose clothes, which are not only warm and soft, but also very comfortable, or you can wear a sweater or sweater if you want to be more fashionable. These two combinations will make the baby more energetic, but it should be noted that the jacket can be thinner because the inner liner of the down jacket is already warmer.
In fact, children's down liner can be worn as both liner and coat, which makes children's childishness cute. However, it is recommended to wear it indoors and outdoors, and it is best to wear a coat when outdoors to avoid being easily stained or scratched. Moreover, parents should increase or decrease clothes for their babies according to the weather and body temperature to ensure their babies keep warm.
