You can also book an economy ticket and waitlist for business for that flight or another flight.
The rules state lapchild fare are only for childern under 2 years of age at time of travel. While you might get away with it if you fudge the child's birthday on the ticket, there is a risk the child will not be allowed to board.
Or if the child looks over 2 in size they may investigate or inquire. My nephew was 2.5 (he's little for his age) and the FA thought he was a lap child and was going to move my sister on an RJ because of the amount of masks but we had to tell and show her his own ticket 2x.
