Babies are unaware of day and night they sleep for most of the time.  
They can move the head from one side to the other, hands are fisted near the face. They suck well, opens mouth at the sight of breast or bottle. Newborns can only be awake for 1-2 hours, nappy has to be changed regularly through the night.
They can only discriminate mothers voice. They will stop crying when we pick them up. They are making throaty noises. 

From the 3 months, babies are getting much more alert and responsive. They can roll to sides, hands unfisted 50%, reaching for the face. Brings hand to mouth. They are more aware of the toys, and can visually follow the person around the room.
They can recognise family voices, they vocalise when talked to. Most babies wake up between 3-4 hours at night for a feed.  

At around 4- 6   months sleep patterns are starting to change, less REM sleep. Babies are learning how to roll from front to back. Starts to look longer at new faces than familiar.

Babies are eating more food and experimenting with textures (Wilks et al., 2010). It’s a very busy time for babies, they can start waking up more frequently during the night. Babies at this age naps 3 times a day morning, lunchtime and afternoon. 

Around 9 months babies are starting to crawl, shuffle or even walking. They are getting stronger, can pull themselves, can bang two cubes together. They like to pull them self-up in their crib.

They can feed themselves, and they have the same diet as everyone else in the family. They point to an object they want to get, they will vocalise what they want. They have more teeth coming which can be painful and uncomfortable. They will nap twice a day, and still eat in the night.
