All by themselves: sitting up
By the time your baby is around seven months old they're likely to be able to sit unsupported for short periods of time. They'll also be able to sit in a high chair - just be careful not to leave them unattended as they can still lose their balance easily.
Excuse me: learning to burp
It’s likely your baby will be able burp his or her self by this time. Again, there's no set date for when this should happen, if they still need your help that's fine. Gently patting them on the back should be enough. If they haven't burped after a couple of minutes, they probably don’t need to!
Tricky little movements: fine motor skills
By seven months or so, your baby's communication and coordination skills will be coming along in leaps and bounds. You might notice they have better control of their hands. They'll probably be able to hold a two handled cup and drink by themselves, maybe grip things better or even clap. These are known as fine motor skills, which use small, precise movements of thumbs and fingers. Fine motor skills also include small tongue movements, like you do when you taste something. These may be slowly coming along, but they’ll play a big part in your baby learning to talk.
