Night time routine with starting solids

Baby boy just turned 6 months. Want to start introducing solids. He is EBF and don't plan on stopping for a bit longer. Our current night time routine (which works great for us!) Is warm washcloth, massage, playtime/read then nurse before bed and put down sleepy. He's in bed by 7pm and sleeps for 10-12 hours now so I don't want to mess this up lol. When should I feeding him solids? I don't usually get home from work til 6 pm btw
