Parenting advice from a ten year old

Ok so this is something that is annoying me and I have to share

So as if I don’t get enough criticism from my mil and sil, my 10 year old nephew has jumped on the bandwagon and is offering me parenting advice. I know it seems silly to be annoyed by it, but I feel like the only reason he is doing it is because his mom and grandma do it too

He told me I need to spank my son, that I don’t discipline him enough. He even offered to spank my son for me (I don’t spank) he told me I need to take my son to a barber shop because he doesn’t think my mom does a good job cutting his hair (I like his hair and my moms a professional hair cutter). He told me I need to give my son what we are eating for dinner instead of making him “special meals” (my son has autism andARFID he only eats 3 foods, this has been my biggest struggle with my son and I am honestly so tired of hearing about it, he has been is “feeding therapy” for about 7 months with no progress so anytime someone mentions his eating I legit want to cry)

This is really just the gist of it. I know it sounds so stupid to be annoyed by my nephew bc he is just a child himself, but I feel like I am such a failure that even a ten year old is correcting me.

My son is 2 btw
