I only use it for her gas, I'm not sure the reason you're using it but for her I just do it as needed when her belly is hurting. I haven't noticed a difference it doesn't make her sleepy or anything (:
My aunt breast fed all her kids and she said the generic brand was the best for all her kids the little remedies one never worked for her!
You use it like after a feeding? He always squirms around like if his belly is hurting @kparis
