We have PT Dash and I didnt have issues getting DS2 in and out etc while in the coccoon would put him it that then slide him in and out in that. Once he was too big for that i pretty much put him into the toddler seat on the back with the zip part fully undone to lie him back as much as it would but was still sitting up. This was about 4 months.

I still use my phil and ted most days with a nearly 3 year old and a 15 month old.
