Aww, that age is so tricky kasi they're past the newborn sleepiness na! A few of us moms tried motion, like walking around, using a baby carrier, or even sitting on the exercise ball while bouncing gently, and it worked better than white noise alone para sa aming wakeful babies. You can also try adjusting feeding times or checking if she's overtired (counterintuitive but true!), kasi sometimes a very alert baby just needs help settling down para makatulog talaga. Don't worry, this phase usually gets better, but if you're really concerned about her sleep or feeding, best to check with your pedia just to make sure everything's okay! Hugs, first-time parenting is hard talaga.
