Firstly, you would be surprised how many members have come here based on referrals from baby forums.
It is not uncommon early after discovery for a WS to go through mood swings on steroids, flipping back and forth between apparent remorse (which is really just guilt) and the AP, with the occasional stops to attempt to rugsweep everything. He may also be worried about the safety of your child and just be trying not to upset you so you don't have to medicate as often.
There is also a possibility that he has bought another cellphone in the last few days and is using that instead so that you do not see the calls on the bill.
For the sake of your health and that of your child, you may want to look into the 180. I don't mean the passive aggressive crap that often gets passed off as the 180, where you are trying to manipulate the WS, but the genuine focus on strengthening yourself so you will be alright regardless of what the outcome is with him. The essence of it all is in this nice little acronym we have here.
Do not back up. Severe tire damage.
I noticed that on the days that XWH didn't have phone communication with OW (according to phone records) it was because he was with her.
Sad but very true.
Never forget what is worth remembering or remember what is best forgotten.
Do you know if the OW is married or has a boyfriend? If so some have found it useful to tell the spouse or SO of the OW as it can sometimes helps get things shut down.
You may find it useful to read Shirley Glass' book "Not Just Friends" with your SO. It might help him realize that what he's doing is totally inappropriate and that he's playing with fire.
