Kebble and partner Olivia welcomed Lachlan into the world a few weeks ago, causing the prop to miss the Champions Cup tie with Northampton.
Kebble was back in action in the Challenge Cup win over Bayonne and in last Friday's victory over Edinburgh in the first leg of the 1872 Cup.
With Lachlan's arrival it's been a quieter festive season than usual for the Kebble family.
"It's the best thing I've ever done becoming a dad and it's an amazing feeling," said Kebble in The Scotsman. "It's my first kid and the first grandkid for both sides of the family so he got spoiled rotten this Christmas.
"We've so many teammates with kids and they've warned me about how tired I'll be for training. It's not actually been that bad because my expectations were so low and I prepared for the worse.
"You just adapt to the tiredness and you feel a huge sense of purpose with the baby - it's different from having a hangover from an all-nighter! It's certainly different from last year's Christmas when we were in the pub and having a beer. It was bottle feeding this year and lying on the couch.
"You feel like you've actually done something when looking after a kid so it's great. I've always been highly motivated playing for Glasgow but it's definitely given me more perspective and shown me what's important in life. I'm enjoying my rugby as much as ever."
Glasgow vs Edinburgh matches are always viewed through the prism of who puts themselves in the mix for Scotland selection so Kebble admits it was good to see the Warriors pack have the upper hand for the most part on Friday night.
"We were warming up right behind the pack and we all went ballistic [after the first one]," he added. "It's obviously a key part of the game against Edinburgh because whoever wins the set-piece battle will likely come out on top.
"You've got two Scotland front rows going against each other and it's almost like a Scotland trial match on the sideline. I wouldn't say we came out on top but we did well in our battles.
"We play against the same guys so as seasoned campaigners, it's the same playing Pierre [Schoeman] and WP [Nel] as it is playing the Irish lads because you play them all the time."
Kebble says he's been working hard to make himself a regular fixture in Glasgow's matchday squad after drifting in and out of the picture last season.
"I've been working hard in the background but I made it clear in pre-season that I wasn't up to speed last year," he added. "I started well this year on the loosehead side and now I'm helping out at tighthead.
"It's about giving back as much as I can to this club and I'll play anywhere, maybe even No.10 next week."
