Advice on Starting the Solid Food Journey

So, our little guy was given the clear to start trying solid foods soon. I’m going to be making my own baby food (I already meal prep so it’s not a huge undertaking for me). Does anybody have any advice? Should I keep some baby Benadryl in case he’s allergic to something? Is baby Benadryl even a thing? I have read some brief online blurbs but they’re pretty vague....Am I worrying too much? Well that last question I’m sure is a given. Thanks in advance for any info you guys have!
