Hi again, she has 1 hr and quarter to one and half hours activity time, but she is touchy so half an hour prior to bed we have cuddles and low key activities. At 10 weeks she could only manage 1hr and 1/4 activity time at the very most, sometimes only hr. It is a bit trial and error, but the ease of which they go to sleep gives you a clue. If it takes ages and your lo is fretful it is likely overtired/stimulated, so cut back slightly on activity time the next time and see if it helps
