Guilt/paranoia over juice

My baby is 29 weeks old so almost 7 months and he’s already slowly starting solids, however he seems to be more interested in the food that I eat instead of what I offer him. Last night he started grabbing for and crying over my juice. I was trying to hide the glass but somehow my husband made me give him a sip just to shut him up, which he did and he was all laughs after that. I know I absolutely shouldn’t have caved in and I’m feeling so guilty now because not only was it not homemade juice but it was also quite sweet 😩 I hope it doesn’t do him any harm and will never do it again. I swear since we started introducing solids my anxiety is through the roof 😥
