Also would have to include what difficulty your playing in as the spawns are different for each.

I noticed this as well except I was able to just sprint off of every ladder straight on the only 2 ladders that I can think of that force you to go down them properly is the one in the doll house in the sewer like area, and the second is in the factory where you've just pulled the 2nd level lever for Duke.

@XTerminator I don't what you mean by hiding from the baby i've always just looped around back through the hole you cut with the scissors and open the breaker box then. But yes after placing the fuse in box you can just wait at the elevator and if I remember right the door auto opens so you just have to get in and press the button.

@PizzaSHARK Im at school and cant comment on everything but wanted to tell everyone that guarding negates grab animations so when I see the arm raised or both coming to hug me I hold guard until I am hit then let go.

Yea sorry that was a poor choice of words I meant you can be faster than the baby and put the relief of a child in the door before the baby can get you not actually kill it lol. and thanks @JohnnyNewYork You got what I meant

So after a few more hours of testing @Zengro 's way of clearing it makes it pretty consistent on getting under 4 mins and like @TrashWolf said running around killing them all or even just dodging and blocking makes the encounter last longer. So still searching for the exact checkpoints to progress

I want to add that you can beat the baby and put the Relief of a child in the door.

What I've found is that the whole encounter takes about 4min 20 sec to complete so far. You can also sit on the ladder in the second house to stop taking any damage however it does not activate the checkpoint for the big lycan and might not pass any time of this 4min 20 sec. Will be doing further testing.
