At 6 months, babies continue to explore the world around them, and their physical activity increases. 

Here's what a 6 month milestones infants typically do:

1. A baby can reach out their arms toward you and push themselves up using their forearms. They have a strong grip and can grasp objects with both hands, except for the thumb. When lying on their back, they can even grab their own legs.

2. Fine motor skills are rapidly developing. Babies may explore toys by putting them in their mouths, and they might throw objects on the floor to observe what happens. Parents should be cautious with small objects.

3. Rolling over from their back to their tummy and vice versa becomes effortless, as their muscular system strengthens, making them more mobile. Babies develop strong neck, arm, and back muscles that allow them to turn without difficulty.

4. Many babies start sitting up on their own or attempt to do so.

Tips for parents

1. If your 6-month-old baby hasn't started sitting up yet, don't rush them. Some children need more time to develop this skill. Instead of forcing them, try to spark their interest. For instance, hang a toy on the side of the crib, encouraging them to sit up to reach it.

2. If your baby isn't rolling over at 6 months, consult a pediatrician. They may require assistance, such as special exercises or massage, to develop this skill.

3. If your baby is already attempting to stand at 6 months, there's generally no need to worry. If they achieved these 6 months old baby developmental milestones independently, it's a sign of their readiness. However, if you're concerned, consult a neurologist.

4. At this stage, your baby is improving their motor skills and showing increased interest in their surroundings. Encourage this development by stimulating their fine motor skills and cognitive abilities. For instance, when your baby holds two toys in their hands, offer them a third one. Initially, they may try to grab it without letting go of the first two. Over time, they'll learn to free up a hand to reach for the third toy.

5. Many parents wonder if jumpers are suitable for 6 months old baby developmental milestones. Orthopedists recommend not rushing into this. Your baby's spine and muscles may not be sufficiently developed to handle the strain of a jumper. It's advisable to start using jumpers only when your child can confidently sit without support and stop using them when your child begins to walk independently. If your child has orthopedic or neurological issues, it's best to avoid using jumpers for babies aged 6 months and older.

The 6 months old baby developmental milestones mean that a baby largely depends on their overall well-being. If your baby is healthy, they are likely to progress through these stages without significant issues. However, if you have any concerns about your baby's development, don't hesitate to seek guidance from your pediatrician. Remember that attentive and caring parents play a crucial role in supporting their child's growth and development.
