For us, I always found that EWs and NWs were OT related, but I think we're an exception to the norm - I think for most these are a sign of UT. That said, if she was having some crazy early EWs then I suspect she is probably OT by this point.
I would maybe let her nap as along as she needs for a few days to observe and if the un-capped naps cause BT shenanigans, NWs, or EWs then I def think it's UT and it might be time to start capping.
What do you think?
