Need advice for airplane connection

We have a trip in a couple weeks where we will be taking our 3 year old and 8 month old.

When originally booked, we had a layover of 2+ hours. This was especially important because we will be taking carseats on the plane (multiple reasons - there's no way logistically around this).

American ended up changing our second flight time and moved it up. We will be landing in Philadelphia (assuming no delays) at 9:45a, and now our second plane takes off at 10:52a.

I've never been to Philadelphia airport before. In my mind, boarding will close at 10:37, which gives us at most 52 minutes to deplane, lug carseats, and find our gate. Our seats are right in the middle of the plane for both flights.

My husband and I have flown several times, but this is our first time with kids.

Can someone please give advice on making this connection assuming there aren't any delays? Anything logistically? I'm planning on having the 3 year old use the bathroom on the first plane before landing. Anyone also familiar with Philadelphia airport & what it's like?

If you think I'm a little anxious about this you would be correct lol. Rescheduling the 2nd flight to a later time would be $900+ which isn't something we can really do right now.

Anyone who can give peace of mind or advice, it would be greatly appreciated as I'm a newbie at traveling with kids. Thank you!!!
