Hi and welcome.

Could you post what yesterday looked like for me in real time in easy format so it's easier to read please? So looking like this:
wu 4.30 (including what you did to try and resettle)
up at ...
A 2hr
S from when to when etc etc all the way to BT and any NW's too
It does sound like he's UT for that first nap, but I just want to check your easy to make sure. EW is usually a sign the first nap is too early and they deal with it by stretching their own A time as frustrating as it is. I look forward to hearing from you and then we'll make a plan ok? ((hugs)) in the meantime, 4.30am WU's are the pits xx
