Ay oo, normal yan, mama! Around 7 months kasi, they're developing better sleep-wake cycles na, so mas mahabang stretches ng gising at deeper sleep during night time, a few of us noticed the same thing with our babies around that age. Basta monitor mo lang kung siya ay happy, playful, and getting enough feeds throughout the day, then you're good to go! If you're worried about anything else, like if she seems cranky or the wake windows don't match her feeding schedule, mas better to run it by your doc lang para sa peace of mind.
