Hello, lovely ladies - Moms! Could you please tell me, has anyone ever experienced... Baby almost a year old, since yesterday he started noticing that when the baby wakes up, he starts squinting (as if trying to focus his vision on some detail). We haven't seen this before. Either I have "paranoia" and he's just sleepy, or we need to go see an ophthalmologist. In any case, we will visit him. But maybe someone had a similar experience and knows what it all means?
