Puberty in girls

During parenting you experience many things while watching your kids grow. Infant (0 to 1 years old), toddler (1 to 3 years old), early childhood (4 to 8 years old), middle childhood (9 to 11 years old) and adolescence (12 to 18 years old), as each stage passes you observe some mental and physical development in your child. During the first three stages (Infant, toddler and early childhood) kids generally go through many natural physical changes of growth. These first 8 years of kids are extremely important for their healthy development and lifelong learnings. Cognitive, social, emotional, language and physical development during this time plays an important role in their life. At every stage a child needs you to understand the learnings and changes that they are experiencing around them. As they enter the puberty phase it becomes more important to be with them. This is the time for some major physical and hormonal changes, which may pop up some questions, which have to be answered properly, But the main question is what puberty is and at what age puberty starts?

What is Puberty? At what age puberty starts?

Puberty is the time when a boy or girl goes through a series of biological and physical transformations. Everyone has experienced this phase in life. It is a transition from childhood to adolescence. Teens go through some changes in their body and hormone levels during this phase. Puberty often begins early in girls as it falls between the ages of 8 to 13 in them. Although every girl has her own unique journey and puberty timing differs in each girl, it definitely brings some hormonal, physical and emotional changes in girls which are absolutely normal. 8 years of age sounds really young for seeing any physical changes. So, it is a little bit awkward to discuss puberty stages and the female reproductive system with your young girls, but it is important to start educating them on these topics before changes happen to best prepare them. It will make them much more comfortable to understand and accept the changes.

Sings of puberty among girls

It is normal for the left and right breast to grow at different speeds. Its also normal for breast buds to be tender or sore, usually it improves with time. A sports bra can be a good choice to wear at this stage.

Body hair: In about 15-20% girls public hairs may be the first sign of puberty. These hairs begin to grow under the arms, around genital areas and on the legs. It is another sign of puberty among girls.

Vaginal discharge: This is a sign of growing numbers of estrogen hormones in the body. Girls experience a small amount of clear or white vaginal discharge that starts about 6-12 months before their first periods. It is considered as a sign of puberty among girls.

Periods: Girls usually get their first periods within 1-2 years after the development of breast buds. It is important to be aware that periods are a normal natural process of growing up.
