Hi, welcome
At this age, really A time is only going to fit a feed and nappy change. The main thing at this point is simply to have the order EAS happening. That sets up some predictability for LO and will set you in good stead for when A times become a bit more relevant.
At some point before 3 months, LO will 'wake up' from that sleepy newborn phase (some like my DS never really have them) and they will slowing increase A time to around 1.5hr by 3 months and 2hr by 4 months. If you increase gradually by watching the clock to see when sleep cues are likely (watch the LO from about 10min before you'd expect cues) then put LO down for a nap when you see the cues, the increase could happen a bit more gently and naturally.
Congratulations on your new baby, best wishes, we're always here to help out if you need it
