1. Monk-style outfit (0-3M): Similar to a butterfly outfit, but a two-piece set. In hot summer weather, pants can be omitted. However, I personally prefer the butterfly outfit.

2. Butterfly outfit (0-3M): I think this is the most suitable for newborns. It's a good option; there are few buttons, only ties, and it's a one-piece, so you don't have to worry about it not fitting. It's also very convenient for diaper changes.

3. Onesie (0-12M): Suitable for summer, making it easy to hold and crawl the baby. However, most onesies are pullovers, which I don't recommend for newborns, mainly because their head and neck bones are not fully developed. You can buy a few after one month. (But I personally suggest waiting until the baby is 3 months old before wearing this type.) Snap-button ones are more suitable for autumn and winter layering. They come in long and short sleeves, and after 6 months, it's more convenient for the baby to wear a two-piece set.

(Avoid pullover onesies and footed onesies; they're difficult to put on and uncomfortable. Also avoid ones with zippers, as they can easily get stuck on small babies.)

4. Two-piece outfits (3M+) Babies over 3 months can wear two-piece outfits. If it's a pullover, choose one with buttons on the shoulders; some babies have larger heads, making it easier to put on and take off.

Regarding sizing (see picture 1 for details):

Expectant mothers are advised to primarily buy size 52, and have 1-2 size 59 items on hand (if giving as gifts, size 59 is recommended; choose larger rather than smaller).

Also, here are some details for choosing clothes!!!

1. Choose Class A, preferably first-class quality.

2. Avoid overly bright colors. Wash new clothes first (when I had my baby, I hand-washed clothes at least 3 times).

3. Baby clothes should ideally have tags sewn on the outside.

4. If it's a pullover, it's best to have buttons on the shoulders.

5. No fluorescent agents, and seamless stitching.

Don't buy very cheap clothes; they'll stiffen after a few washes. However, babies grow quickly, so there's no need for particularly expensive clothes.

So, how should newborns be dressed in different temperatures? How do you determine if a baby is dressed appropriately? Feel the back of the baby's neck or back; generally, a warm temperature is just right. If it's ice-cold, it's too cold.

If there's sweat, consider whether the baby is too hot; in this case, change the swaddle or add/remove clothing as needed. Attention!! Do not use the temperature of your baby's hands and feet as a reference!

This is because a newborn's peripheral circulation is not yet fully developed.

Special Note: Analyze your baby's specific situation and avoid overdressing. Especially in summer, many mothers wrap their babies in several layers to prevent them from getting too hot and developing eczema or prickly heat. However, there is a medical condition called "infant overheating syndrome," which refers to a baby's body temperature becoming too high due to excessive clothing and blankets, resulting in excessive sweating, pale complexion, high fever, convulsions, and even coma. In severe cases, it can damage brain cells and affect the development of the nervous system. Therefore, new mothers must pay attention!
