My first baby didnt engage until i was in labour!!! ( i was induced), the second engaged to 2/5 (im sure thats how they put it) at 34ish weeks and i was induced at 38 weeks. Both were straight forward vajayjay births.
At my last appointment this baby wasnt engaged but im sure it is now because i felt a bit of a drop and now im always getting pressure way down!
Sorry no tips here though, i just went with the flow
