Feeding

My son is 24 weeks and 6 days only (5 months) hell be 6 months old in 10 days, my partner has asked if we could start trying him with small amounts of food or if we should wait until he's 6 month old, I wasn't sure so I thought I would ask as I dont want to start to early if it will cause problems, we know hes ready for it as he watches everyone eat and is trying to get our food aswel could we start now or is it best to just wait the 10 days if its okay what sort of things should we start with
