I'm worried about my child because I can barely eat anything normal throughout the day... I might have one salad or an egg for lunch and only eat fruits like watermelon, apples, grapes, etc. But again, it's not always and not every day, but it happens often when it's a first weekend and I don't feel like cooking, just lying down ??‍♀️ I worry that he might be hungry because of me...or is this all in my head ??‍♀️?
