When to move baby from carrycot?

I have a bugaboo bee3 and my 14w old is currently in the carrycot. He sleeps great in it but spits up right after a feed (if we’re rushing out the door and no time to keep him upright). He is more and more interested in his surroundings. When did you move your little ones out of the cot and into the seat? (I bought it 2nd hand so no manual).
