Other/i Am Not Sure problem

The seat is able to forward face up to 40 lbs with a seatbelt install and 35 lbs with a latch install. When trying to install this seat with the seatbelt the instruction manual states not to lock the seatbelt after install however if the seatbelt inst not locked the seatbelt moves easily with some pressure (I. E. Child pushing legs against back seat) and then becomes so lose that is can fall over. Alternately, I have tried the install with locking the seatbelt and this solution only lasts 1-2 car rides longer. (I. E. I would need to reinstall my seat every other time my child rode in the car). Currently the seat is installed with the latch system as this is the only way to get a safe install however my son is currently 34lbs and it will soon be unsafe to ride rear facing with the latch system which will then force me to turn him front facing before I or my son are ready.
