I felt like I am failing. BLW at 9months

I started solids with babe at 8months. And only feed him twice a day. Because I still prioritized his milk intake. I do prep meal and the effort is just too much sometimes. I love it. I love doing it but sometimes he declined his plate and it hurts me. I don’t know what to do sometimes. I follow solid starts and read few of their articles. I’m just worried that my son will be picky which I follow how to avoid a picky eater from solidstarts. Or 9months is really a learning process to eat until 12months. FTM here. So please, be kind.
