The actor, who plays Darren Osborne on the Channel 4 soap, celebrated becoming a second-time father on 1 October when fiancée Karen McKay gave birth to Mason Mac Taylor Dawson.
They are already parents to son Buddy Mac.
Today, Ashley tweeted: "Thanks again for all the lovely messages of support. Mum and baby are doing just fine. Little Buddy Mac is loving his little bro! #toosweet."
Ashley also tweeted a few days ago: "Really overwhelmed by everything in my life right now, including all your support on Twitter! Can't thank you enough! So so happy XBIG LOVEX."
It's a busy time in the Taylor Dawson household as not only is Ashley getting to grips with baby number two, he's also filming Hollyoaks and putting in serious rehearsal time for Strictly Come Dancing!
The actor is partnered with Ola Jordan on the current series of the BBC One dancing competition, and will take to the dancefloor for the second time this weekend.
It's already been announced they'll be performing an American Smooth to the tune of 'Beyond The Sea'.
Ashley and the other celebrities will be dancing for survival this week, as Sunday night's episode will see the return of the dance-off and the departure of the first celebrity.
Matt Goss will provide the music for the night, singing a special version of 'When Will I Be Famous'.
