My LO is exactly the same, small 30 minute naps in the morning. We go for a walk about 12 and he crashes and has a big sleep in the afternoon.
My baby is also 8 weeks and most of our days are like yours ☺️ she has started getting more awake though the last days so I would like to believe it is how they grow! I was really stressing initially as my first baby was fully awake from the first few days but the more I discuss it the more I realise there is a reason why they call it the 4th trimester!!
Very similar routine here too
I have a 6 week old LG and she has tiny tiny wake windows. She sleeps a lot during the day. X
