The only safe way to transport a child in the front passenger seat of a 2007 Ford Focus is to use a rear-facing car seat in the back seat. This is the safest option for infants and toddlers.
Placing a child in the front passenger seat with the airbag active is extremely dangerous. The force of a deploying airbag could seriously injure or kill a child.
If you must have a child in the front seat (which is strongly discouraged), you should first consult your owner's manual to see if there are any *specific* instructions or warnings regarding child seats and passenger-side airbags. However, it is highly unlikely that the manual will endorse this as a safe practice.
Your safest bet is to always use the rear seats for children. If the rear seats are unavailable, you need to find alternative transportation that can accommodate your family safely.
