It’s baby number four for Guiding Light‘s Daniel Cosgrove and his wife Marie. The couple welcomed their first son, Finnian Jack Cosgrove, on Wednesday, March 4th. He joins big sisters Lily, 8, Esme Rose, 6 and Ruby Willow, 3 ½.

Daniel, 38, joined the daytime serial in the role of Bill Lewis in 2002, but left the show in 2005 when his contract expired. He returned to GL in 2007. Finnian will not be the only baby on the Guiding Light set, as Daniel’s co-star Jessica Leccia is currently expecting her first child — due in June — and Bradley Cole welcomed daughter Maya Joan in February.
