Under my 4 month baby eyes is swollen since born.. Any idea on it

Aww, I understand your concern, mama, it is always a little worrying when we notice something different about our little ones. From what I have heard, some puffiness under the eyes can be normal right after birth, but if it has stayed since she was born and is still there at 4 months, that is worth paying closer attention to. Someone in my mum group mentioned it could be blocked tear ducts, and they suggested gently applying a warm compress near the eye area when baby wakes up in the morning, which apparently helped quite a bit. It is also good to observe whether the swelling comes and goes, or if there are other symptoms like crustiness, redness, or discharge, as those extra signs can help the doctor understand better. Do bring it up with your paediatrician soon, sayang, they will be able to give the most accurate guidance for your baby girl specifically.
