When to establish nap routine?

My 2.5 month old baby also have short 30min naps. I am abit thankful for this as it means she can sleep longer at night with stretches of 4-5hours at night. I’ve tried white noise, aircon, swaddling to make her naps longer but to no success, so i figured she wants short naps so that she can wake up to play and drink milk in between ☺️
