Your baby is becoming more mobile and as a result, is learning to crawl and move like a real pro.

What you can do:

You can provide your active baby with stacking toys: blocks, nesting boxes, and clean, empty food containers with no sharp edges. Some babies at this age love pull-toys, and age-old favourite games such as peek-a-boo and pat-a-cake. In addition, babies love having books to play with and look at (board books made of plastic or stiff cardboard are best).

This month, some babies may:

• Roll a ball to you as their social skills and interest in play continues to grow.
• Go from lying to sitting without any help.
• Show a desire to please you as they become even more attached to you. The trust, love and connection between your baby and you are continuing to grow.
• Search for a toy after watching you hide it. Your baby is beginning to understand object permanence - the idea that an object exists even when it cannot be seen.
• Resist being put to bed or left alone as their attachment to you grows.
• Remember a favourite song, and laugh and smile when it's played.
• Express themselves with gestures and sounds instead of cries.
• Use gibberish in a conversational way.

The skills described above generally appear during the indicated time frame. But don't worry -all babies are unique and develop at different rates. Talk to your doctor if you become concerned about your baby's health and development - at any time.
