INVESTING STRATEGY

Hi Pearler community, Iv started this year investing into etfs and have been learning about all there is to know about etfs and the stockmarket and have been really keen and interested and still learning. Currently in late 30s with a young family and a mortgage that were also focused on paying off. Currently invested into Vgs and Vas using DCA.However I'm looking for further reducing risk as well as additional diversification into other asset classes both in Aus and overseas by adding additional etfs for the time being. Is anyone looking into bonds ie iaf (or femx fund), Reits or emerging markets for growth and hopefully Income to even out the downturns in the market in my portfolio. I understand everyone has their own investment strategy,goals,risk tolerance and path based on their own situations so was just wondering people's thoughts and what they use? Just wanting to keep things simple so looking currently at a 3-4 ETF/managed fund portfolio that I can keep DCA into for the next 10 years and onwards. Much appreciated
