Aww, mama, don't worry, you're doing your best and that's what matters! Sa edad na yan, pwede mo try ang mas masarap at mataas-calorie snacks like banana with peanut butter, scrambled eggs, cheese, avocado, or sweet potato, anything na mahilig siya at makakagana. I'd really suggest checking with your pedia though kasi they can give you the best guidance kung ano talaga kailangan ng baby mo based sa growth chart niya, and maybe may specific foods or formula adjustment na kailangan. You've got this, mama, ang fact na concerned ka means you're a great mom already!
