Is it normal that my baby is not sitting or crawling at 7 months?

In brief: Yes

Crawling would be a little advanced at 7 months (9 months is the "normal").
With any milestone, the age given is the age at which the "average" infant can to do it. That leaves a pretty wide range. For sitting without support, the milestone is 6 months. In general, as long as the milestone is met before the next milestone is due (in this case, at 9 months) it still falls in the normal range.

In brief: Yes

Usually around 6 months is when babies begin to crawl.
Remember that scooting, crawling backward and rolling around to get from place to place all qualify as crawling. Babies at 7 months need only to sit unsupported for 30 seconds to be doing these skills well. If your child cannot do either of these skills well then seeing a pediatrician for formal screening is a good idea.

In brief: No

Most babies sit at 6 months.
Crawling comes a bit later. A baby who is not sitting at 7 months can see the doctor to recheck the motor skills development pattern since birth, to see if there is a problem or not. Being one month late on sitting or crawling can be ok, if other skills are developing fine, and the baby is not weak nor soft in the muscle tone.

In brief: No

Your baby should be sitting with support by this point and getting better at attempts without support.
With daily practice and positioning, he should be improving.. As for the crawling, if he has not been put on his belly often to make attempts, the crawling may not happen at all.

In brief: Yes

Yes - this is not uncommon.
'sitting' at 6-7 months usually means they only stay up with hands propped to the front. They fall sideways and backwards. Average 9 month old's sit well in all directions. 9 months is average for crawling but there is a wide range of 'normal' for both milestones.
