Blue smoke is indicative of oil leaking into the chambers (as noted,) and blue smoke only on startup usually indicates either:
- Rings haven't seated yet or have come unseated, or the oil control ring has lost tension and isn't doing its job. Under 15kmiles, it can be "not seated yet." The other two generally don't happen until 200Kmiles or so.
- Valve guide seals have hardened and aren't wiping effectively until they get wet. Add a seal conditioner to correct, works probably 7/10 times.
I would suggest changing your oil, substituting one quart of Marvel Mystery Oil for one quart of engine oil. This should help condition your valve guide seals, which is probably the most likely issue at this point.
I'd dump in the MMO, since it's the much cheaper and easier fix and won't cause any damage if the valve guide seals aren't the problem. It requires no disassembly of anything, save R/I the sump drain plug and the oil filter - easy!
If the MMO helps, you can either continue doing so (won't cause any problem, and can keep other problems at bay as well. Yes, MMO is also compatible with synthetic oils) or do it every fourth or fifth oil change (just keep track.) Doing it every time only adds a few bucks to the cost of your oil change, and usually saves you a pantload in repair bills, so I consider it worthwhile.
