Frequently Asked Questions (FAQ)

1. My 7-month-old baby is not crawling; should I be worried?

Every baby's development process is different. While some babies may start crawling in the 6th month, others may not show signs of crawling until the 9th month. In fact, some babies skip crawling entirely and go straight to walking. Therefore, you do not need to worry if your 7-month-old is not crawling yet. Instead, observe these developmental signals:

• Moving arms and legs freely

• Showing movements like reaching for toys and rolling

• Lifting their head in a prone (tummy time) position

These behaviors indicate that motor skills are developing correctly. However, if your baby is not rolling at all, not using their arms sufficiently, or has very weak muscle tone, it may be beneficial to consult a pediatrician.

2. Are nighttime wakings normal for a 7-month-old?

Yes, it is quite common for 7-month-old babies to still wake up at least once during the night. During this period, sleep may be interrupted due to:

• Teething

• Separation anxiety

• Fatigue caused by the increase in learning and motor skills

To support night sleep:

• Create a calm routine before sleep (bath, light massage, lullaby).

• Ensure the sleeping environment is quiet, dark, and cool.

• Balance daytime sleep; sleeping too long during the day can disrupt night sleep. 

Remember: Night time wakings during this period are temporary and usually linked to development.

3. Which toys should be bought for a 7-month-old baby?

Since 7-month-old babies are beginning to understand cause-and-effect relationships, products that support sensory stimulation and motor skill development should be preferred. 

Examples of suitable toys:

• Teethers and silicone rings

• Soft books that make sounds when pressed

• Stacking plastic boxes

• Colorful balls or large blocks

• Push toys that encourage movement on the floor

When choosing toys, it is important for safety to select products that:

• Have no sharp corners.

• Are large enough not to be swallowed.

• Are BPA-free.

• Are CE certified.
