Extending bedtimes?

Tracy
Hi ladies! Both my husband and I work from 8-5:30ish. My baby wakes up at 6am and goes to bed around 6:30. With commuting and everything, I basically only get 2 hours of awake time with him a day :( Is it advisable to try to extend his bedtime? If so, do you have any tips on how to do it? Or is it better to stick to the bedtime even though it means less active baby/parent time on weekdays? Cutting back hours at work is not an option and there is the possibility that I may have to work more. The lack of time with my kid is really depressing me
