GROWTH PROGRESS:

One way to measure your child's progress and development is through their height and weight. Regular weigh-ins at your clinic or doctor's surgery will give you an idea of how well your baby is doing. While babies vary in how fast they gain weight, you will see the biggest gain during the first six to nine months.
At six to nine months of age your baby may be sleeping around 14 hours in every 24 hours including two daytime naps.
Your baby will be learning how to get around by crawling. He/she may start by crawling backwards, or may not crawl at all but bottom shuffle instead. He/she'll be able to sit without support, and by the time he/she's nine months old may be able to pull his/herself up to stand using furniture or your helping hands.
Around about nine months of age, most babies are able to stay upright, sitting on the floor, for several minutes. If they topple over, they can usually get themselves back into position. Your baby can pull themselves to standing if they can reach the right item to help, such as a stool or chair, but they can’t get themselves down except by falling.
Other physical developments between 6 and 12 months:     

• They start to look for toys, including ones that have fallen out of sight, and then by a year, they understand that an object can ‘hide’ under a cup or a scarf. They can retrieve it, and even show surprise if it’s not there.
• They can deliberately throw things from the pram, to watch them fall, and to enjoy watching the adult pick them up again.
