Ethan is laying in my arms, it's almost bed time and his eyelids are starting to droop (yay! finally!)

I'm looking at his eyes, and his pupils are changing size!!!alternating from not much bigger than a match head, to huge so it takes up half the iris, then it goes back again.

I have never seem them do this! (and I often look into his eyes!!)

Is this normal? It's almost creepy!!!

Is he opening and closing his eyes? Are you sitting under bright lights? If the pupils are getting larger when his eyes are closed and then gradually shrinking when he opens them, then yes that is normal. It is his pupils reacting to light and dark (behind closed eyelids). If that is not what is happening, then I'd check with a health professional.

there were lights on at the end of tthe room we were in, but it was dim where we were and he was just watching me, blinking every now and then bu not really closing his eyes. ill have a look again today and tonight and if it happens again ill take him in tomorrow

Did you find out what this was? I noticed this in my almost 5 month old the other evening.

they said it was most likely from the light, but i have to take him back in october to get his eyes tested again... ethan is approx the same age as your bub. i wonder if its a developmental thing???
