I don't think it's about the joys of having a child but I can see how it relates to the song itself. To me, I think it's about someone look back on his or her life and realising how much they've wasted and that they haven't lived their life at all. The first stanza is filled with powerful sensory imagery and each line ...with "mono", no looking back, it's like they were restricted and limited by only one choice in their life, they weren't getting anywhere. All their decisions and actions led them to the same destination at the end of their journey. "Monochrome" suggesting how black and white their world was and "monotone" suggesting lack of emotion hence emphasising a lack of life. They felt like they had nothing to live for and they took to drinking booze. Then they consumed themselves with despair when "I lay there in the dark and I close my eyes". Then someone or something that was probably in the same situation as him in the dark like himself probably showed them that their life wasn't just black and white and didn't lack of colour, and it allowed them to 'come alive'. This gave them inspiration to change themselves and they too began to ‘come alive’ as well and thus they began to feel compared to when "I could hardly feel me anymore", they weren't in touch with their senses. Senses that made them alive. I dunno, but that's how I interpret it unless someone can convince me otherwise or tell me word for word what Grohl meant when he wrote this song.
