Seeking Sorceror Multiclass Suggestions

[NecessaryWeevil]

Hello Playground,

So our campaign now has three arcane casters: an Illusionist Wizard, a Draconic Sorceror, and myself, a Celestial Sorceror. The other players are a barbarian and a ranger, and we're currently on the cusp of third level.

You'll notice that we have little healing. I'd like to help a little in that regard, and I'm trying to find the best solution. I'm thinking about multiclassing into either Bard or Oracle for that purpose. I'm a bit concerned about the loss of caster level, but maybe I can become a healer/buffer/summoner. The other sorceror seems to specialize in blasting and engages in melee, while the wizard has built very well and tends to be pretty versatile in terms of skills and spells.

What do you think? What's the best way to support the party and perhaps bring a little healing (even just downtime / clutch healing) without becoming a one-trick healbot or overshadowed by those who do the same thing but better?

I'm a gnome with high CHA, average WIS and slightly elevated INT.

Thanks!

EDIT: It looks like we'll have little to no opportunity to buy stuff although the DM seems willing to drop moderately-personalized loot.

Since Arcane has a fair representation in your party, you could afford to play around and go with the less beaten path. It wouldn't be the most optimal thing to do, but you could split the different with Sorcerer/Oracle and eventually go into Mystic Theurge. Since you would be multiclassing, you would want to pick Revelations that aren't too reliant on level for usage, such as Combat Healer for a 1/day Quick Cure spell for when you really need it.

Another option to look at is Arcane Savant PrC. You wouldn't be able to get it for a few more levels, but the highlight of the class is that you can add spells from any class list to your spells know. So you can cherry pick stuff from Bards, Druids, Clerics, Rangers and Paladins.

Infernal Healing is a spell you can use on the sorc/wiz list, though the flavour may be an issue for you.

If you want to multiclass then the Thuvian Alchemist (http://www.d20pfsrd.com/classes/prestige-classes/other-paizo/n-r/natural-alchemist) PrC might work, though not until after 5th level. Or Pathfinder Savant (http://archivesofnethys.com/PrestigeClassesDisplay.aspx?ItemName=Pathfinder%20 Savant) likewise, though that one loses a caster level.

If you can (and want to) retrain into the Razmiran Priest (http://archivesofnethys.com/ArchetypeDisplay.aspx?FixedName=Sorcerer%20Razmira n%20Priest) archetype then you can get some more healing without multiclassing at all.
