Our baby's development since birth

For parents it's always important to know if their babies are in line with the actual development of the other babies or if there is a bigger time gap between one of the development, may it be physically, visionally or mentally.

The time frame for certain steps of the baby's development are:

1. smiling
2. focusing the eyes on moving objects
3. moving the head up and down (supporting of the neck muscles)
4. creeping
5. sounds (like babbling)
6. laughing
