Child development (2) - three to six months

Most parents find having a baby from three months very enjoyable. Your baby will have overcome many of the internal 'settling down' processes that newborns have. They are most likely a very social being, who delights in being with you, and you have usually learned enough of your baby's ways and messages to get their responses right most of the time.

Social and emotional development
Your baby has learned that you are the person (or one of the people) who comes a lot of the time to meet their needs, but they don't yet understand that you are a separate person. They still have a notion that the whole of life is happening inside themselves, and they are 'making it all happen'. They easily become overstimulated, so take care - when your baby has too much excitement, they will cry and need to be calmed down.

At four months, your baby:

• Enjoys eye contact and having 'conversations'
• Smiles lots
• Laughs out loud and squeals with delight
• Shows they enjoy life by laughing and kicking their legs
• Likes people
• Is interested in surroundings and activities.

• Rolls over from front to back at about four to six months.
• Is able to lift their head and chest when they are on their tummy by four months.
• When on tummy, will wave legs and arms about.
• Plays with fingers from three to four months.
• Is able to hold objects for brief periods.
• Brings toys and objects to mouth by hand.
• Topples over if put into sitting position.

• Follows you with their eyes, looks from one object to another and focuses on small objects.
• Checks their perception by grasping and mouthing the objects.
• Recognises voices and turns their head towards them.

• Coos and gurgles with pleasure
• Babbles and listens
• Turns head towards sounds.

• Talk to your baby all the time, telling them what you are doing and what different noises are.
• Make faces.
• Blow raspberries on their belly.
• Sing to them.
• Place them on the floor in a safe place, on their tummy, for short periods to play.
• Place them on the floor without a nappy to allow them the freedom to kick.
• Provide them with bright objects to look at, and within reaching distance, so they can accidentally touch them, then try to touch them on purpose.
• Provide a range of things to do, and either change what they are looking at or move them to a different spot so they have something else to look at.
• Place colourful toys nearby so they can look at them, touch them and try to hit them.

• Muscle tone and power unusually low or high
• Fingers not extending spontaneously
• Arms and legs held flexed most of the time

• Lack of adequate weight gain
