A baby's motor development is impressive and rapid in the first months. Many parents wonder: are we progressing well? when will the baby sit up? In this article, we will review the most important milestones and also show you how you can support this process with appropriate baby toys.
2-month-old baby's motor development
A 2-month-old baby starts to explore their own body. When lying on their tummy, they briefly lift their head and observe their surroundings more consciously.
- head lifting when lying on tummy
- eye-tracking
- initial coordination
Contrasting pattern baby toys aid neurological development.
3-month-old baby: more stable movement
A 3-month-old baby's movements are much more controlled. Head control becomes more secure, and the intention to reach for objects emerges.
- propping on forearms
- development of hand-eye coordination
- conscious touching of toys
During this period, daily tummy time is important, so a rattling toy or even a Little Dutch activity ball might be interesting to capture their attention.

4-month-old baby: rolling and active movement
A 4-month-old baby is already trying to roll over. Some babies even roll from their back to their tummy.
- rolling to the side
- strengthening body control
- increased interest in the environment
Baby toys with different textures encourage movement.
5-month-old baby: intensive developmental stage
The 5-month-old baby is increasingly active: reaching, grasping, rolling, and exploring everything.
- conscious object grasping
- more stable rolling
- exploration with the mouth
Safe, multi-shaped baby toys are crucial.
6-month-old baby: when does the baby sit?
The big question: when does the baby sit? A 6-month-old baby is usually able to sit for a short time with support, but independent sitting typically develops later, between 7-9 months of age.
- sitting with support
- strengthening core muscles
- more coordinated movement
Important: don't rush sitting, the natural developmental rhythm is best.
Experts say: every baby develops at a different pace
According to pediatric recommendations, baby's motor development is not a race. The American Academy of Pediatrics emphasizes that milestones are guidelines, but variations are completely normal.
Based on research from the World Health Organization, the development of healthy babies can vary within a wide time frame, so it's not worth comparing them to others.
How to support baby's motor development?
A baby's motor development occurs naturally, but you can consciously assist it:
- provide free movement space every day
- practice tummy time
- choose developmental baby toys
- avoid early sitting

A baby's motor development builds month by month. The 2-month-old baby, 3-month-old baby, 4-month-old baby, 5-month-old baby and 6-month-old baby all go through important milestones. The most important thing is to observe your baby's signals and support them – not rushing, but accompanying them.
