First of all, a big thank you to all who weighed in your thoughts on my question here. There are some common themes to all the replies and I thought I would share it with all those who are trying to juggle multiple things in life with blogging:
1) Have drafts for posts or rough outline ready and fill in the details as when you get time or when creativity strikes.
2) Blog during the day or night, in a coffee shop or on the bus, basically whenever you get time OR have some time set aside for your blog every day or every alternate day. Depending on what your work style is, either approach would be fine.
3) Prioritize Prioritize Prioritize...
4) Have two or three key topics/themes to let your creativity and ideas flow and have a mix of shorter and longer posts.
In the end, if you really LOVE blogging, find it exciting and it gets your adrenaline pumping, you WILL find time for it, no matter what :))
