Many people said their baby bearded dragon eat like 30+ crickets a day. Mine only eats like 2! somethin wrong?

My baby beardie is about 6 or 6 and a half inches long. I feed her in the mornings and evenings. She only eats one per session. then she might eat some lettuce. is something wrong? are the crickets too big? their about the length between her eyes maybe 2 or 3 centimeters bigger. maybe even 1 but their not tooo large. She has two heat lamps and shes getting a 10.0 reptisun uvb light on the 23rd(experts said itd be ok if she didnt have it for 9 days.....i feel bad that hers broke and that the pet store wudnt take it bk, or refund. i didnt hav any mor cash when it happened) She closes one eye and keeps the other eye open sometimes. She did it so i gave her a bath, wash out whatever was in her eye. she stopped. then when i tried to feed her (after i read the 30+ crickets) she closed it again and wudnt eat. ppl said tht she wud starve only on 5 crickets and im feeding her 2!!!! HELP! She poops so i dont think the crickets r too big. if they were too big shed get impacted and wudnt poop, right? she poops sometimes 1-3 times in a 3 day period
