Uy, totally get this, ang postpartum period talaga ay stressful, at ang added pressure from people around you makes it 10x harder! Honestly, a few of us mums went through the same thing, kung saan may relatives or friends na parang lahat ng alam nila about your baby kaya laging may comentaryo o suggestions na nakakainis.
What helped me was setting gentle boundaries, like telling them straight up na grateful ka but you and your partner know what's best for your baby, tapos minsan kailangan mo lang ng quiet time para mag-recover. If the stress is really overwhelming though (like affecting your sleep, mood, or ability to function), definitely talk to your OB because postpartum anxiety/depression is real at treatable, hindi ka naman basta stressed lang.
Be kind sa sarili mo, you're healing, adjusting, at learning all at once, kaya it's okay to tune out the noise.
