HIS JOURNAL SO FAR...
March 19 - Musical nappy changing
Tom has been noting how baby Buzz Michaelangelo loves to have his nappy regualrly changed.
And on Wednesday morning he didn't fail to detail his son's healthy bowel moevements.
My son and I just performed a live version of The Dinosaur That Pooped A Planet. He was the dinosaur and it did not end happily ever after.— tom fletcher (@tommcfly) March 19, 2014
March 18 - Never work with children...
Tom shared that in between penning tunes with Niall, he has been coping with the messy task of taking care of Buzz Michelangelo.
To cope he has been chomping down on sweet treats sent from friends excited about their bundle of joy.
Last night I wrote a song with @NiallOfficial and then went home and got peed on by my son. Loved both!— tom fletcher (@tommcfly) March 18, 2014
March 17 - Playing Yoda
As well as viewing children's classics, family Fletcher equally enjoy a bit of Star Wars it seems.
In between wondering if other father's find bringing up baby as exhausting (and smelly) he sent out messages to get opinions from the Twittersphere.
The All About You singer, who makes up one quarter of Brit Award winning band McFly and was in the middle of tour rehearsal’s with supergroup McBusted before Buzz’s birth, was so excited about his new role that he changed his Twitter bio line to an excited "Dad".
Came home to find my wife feeding our son whilst watching Disney movies. So awesome!— tom fletcher (@tommcfly) March 17, 2014
Anyone else been pooped on already today? No? Just me then. #morningfeed— tom fletcher (@tommcfly) March 17, 2014
Hello to all the other mums and dads out there also on the 3am feed.— tom fletcher (@tommcfly) March 17, 2014
March 16 - Baby brain
Aside from a few toilet accidents, Tom was feeling in love with all that comes with playing doting dad. Even if that meant squeezing in power naps when he could, he tried his hardest (and failed) to remember everything he had to do that day, such as sharing a video starring his sibling.
I'm so so so so completely in love with my son.— tom fletcher (@tommcfly) March 16, 2014

March 15 - First look
My sister's latest vid.— tom fletcher (@tommcfly) March 16, 2014
Tom posted the first picture of their baby, sharing a snap of Buzz holding on to his thumb.
The black and white photo instantly won over Tom's 1.27million followers and was retweeted by Giovanna with the caption, "The men in my life…"
Tom couldn't help but admit how exhausted he was though, still, Buzz's hugs made all the hard work worth it.

It was on Friday that Tom shared his first child had come into the world and apologised for his lack of presence online.
