Not yet able to crawl or sit?

Hello, doctor: I would like to ask you about my daughter, who is currently over 6 months old, weighs 7.5 kg, and is 65 cm tall.
Is this within the normal range? (The pediatricians haven't told me if it's considered normal.) She is not sitting very steadily yet; she can sit for a few seconds before falling over.
She is currently learning to crawl, but she is not quite there yet; she can kneel and jump forward.
I use things that my younger sister likes to attract her attention, and my sister drags her to crawl forward.
I've heard from other mothers of baby girls that girls tend to develop faster, but I don't understand what "faster" means.
Does it mean that both gross and fine motor skills develop quicker than boys? Should I take my daughter for an evaluation? Some of my younger sister's developments include being able to drink from a straw at 6 months, wanting to grab things from me, taking away toys from my sister, which makes her unhappy, and she loves to babble in a playful manner.
At 5 months, she started recognizing people and enjoys playing with her hands and feet...
(I've forgotten some details >"<).
I would like to ask if all of this is considered standard development, or is my daughter really developing slower compared to other baby girls? Should I take her to the hospital? Thank you, doctor!

Hello: The increase in weight and height indicates growth.
According to the growth chart, your daughter's weight is between the 50th and 75th percentiles, while her height is at the 50th percentile, which is currently within the normal range.
For different age groups, if the growth curves for height and weight remain constant, the levels of height and weight are largely influenced by genetic factors.
If there is a drop of two curves or if the measurements fall below the 3rd percentile, a doctor should be consulted.

Development encompasses four major areas: gross motor skills, fine motor skills, language, and social adaptability.
Based on the information provided, your daughter is within the normal range.
For gross motor skills, it is considered normal for a six-month-old to roll over, for a seven to eight-month-old to sit, for a nine-month-old to crawl, and for a twelve-month-old to stand independently and begin walking.
If a child is twelve months old and still cannot crawl, or eighteen months old and still cannot walk, this would be classified as developmental delay and may require rehabilitation.
Development is similar for both boys and girls.
Additionally, babies typically start learning to roll over around four months of age.
Sometimes, when I ask parents, they mention that their seven-month-old baby cannot roll over because the baby is often held or carried.
I encourage parents to help their babies practice rolling over, and they usually learn quickly, after which their gross motor development progresses without issues! Thank you for your letter, and I hope this information is helpful to you!

More Info

When evaluating the development of your 6-month-old daughter, it's important to consider various aspects of growth, including physical measurements, motor skills, and social interactions. Based on the information you provided, your daughter weighs 7.5 kg and measures 65 cm in height. These measurements fall within the normal range according to growth charts, where a weight of 7.5 kg typically places her around the 50th to 75th percentile, and a height of 65 cm is around the 50th percentile for her age. This indicates that her growth is consistent and within expected parameters.

At 6 months, developmental milestones can vary significantly from one child to another. Generally, by this age, infants are expected to be able to sit with support, roll over, and begin to show interest in crawling. Your daughter is currently sitting for a few seconds before toppling over, which is quite normal at this stage. Many babies may not sit independently until they are closer to 7 or 8 months old. The fact that she is beginning to learn to crawl, even if it is in a "jumping" position, is also a positive sign of her developing motor skills.

Regarding the notion that girls may develop faster than boys, it's essential to understand that while there can be trends, each child is unique. Developmental milestones are not strictly defined by gender, and both boys and girls can achieve these milestones at different rates. The key is to observe whether your daughter is progressing over time. If she continues to show improvement in her abilities, that is a good indicator of normal development.

As for your concerns about whether to seek further evaluation, it is generally advisable to consult with a pediatrician if you notice any significant delays in reaching developmental milestones. For instance, if your daughter is not showing progress in her ability to sit or crawl by the time she is 9 months old, or if she is not standing by 12 months, it may warrant further assessment. However, based on your description, she appears to be on track for her age.

In terms of social and cognitive development, you mentioned that she enjoys interacting with her sister and is beginning to understand social cues, such as taking toys and engaging in play. These behaviors are also typical for her age and indicate that she is developing her social skills.

In summary, your daughter's growth and development seem to be within normal limits for her age. It is crucial to continue monitoring her progress and provide her with opportunities for play and exploration, as these experiences are vital for her development. If you have ongoing concerns or if you notice any regression in her abilities, do not hesitate to reach out to your pediatrician for further guidance. Regular check-ups will also help ensure that she is meeting her developmental milestones and receiving the necessary support as she grows.
