Your baby’s physical development will be very quick for the first two years. When your baby is born their movement will only be based on reflexes. Their hands will be fisted and their legs and arms will be in a curled position. But, as the muscles strengthen and the limbs straighten over the first six weeks, you should notice a big change. The first physical challenge that your baby will face is to increase the strength in the head and neck.
The parts of the brain that control movement develop in a sequence from head to toe. This is the reason that babies develop skills in a certain order. The easiest way to know how to stimulate your baby, what games to play and what toys may be best, is to have an understanding of the order of these milestones. If you know what baby should be achieving next, the rest is easy.
