A fatty tissue on new born baby's back
You're referring to a common phenomenon in newborn babies!
The fatty tissue you're referring to is likely a "lanugo" or "lanugo fat." Lanugo is a thick, soft, and waxy substance that covers the skin of many newborn babies, particularly on their back, shoulders, and arms. It's a normal part of fetal development and usually disappears within a few weeks after birth.
Here are some interesting facts about lanugo:
- Purpose: Lanugo serves as a protective barrier, helping to prevent friction and irritation between the skin and the womb. It also helps to regulate body temperature and prevent heat loss.
- Appearance: Lanugo can appear as a thin, white or yellowish layer on the skin, often with a slightly greasy texture. It can be more prominent in areas with more fat, like the back and shoulders.
- Timing: Lanugo typically starts to develop around the 12th week of gestation and continues to grow until birth. It usually starts to fade away within the first few weeks after birth, with most of it gone by 2-3 months.
- Variation: Not all babies have lanugo, and its thickness and distribution can vary significantly from one baby to another. Some babies may have more lanugo on their back, while others may have more on their arms or legs.
- No cause for concern: Lanugo is a normal and harmless phenomenon. It doesn't require any treatment or intervention, and it will naturally resolve on its own as the baby grows and develops.
So, if you notice lanugo on your newborn baby's back, don't worry! It's just a normal part of their development, and it will soon disappear as they grow and thrive.
