GOI specification as below:
http://passport.gov.in/oci/Photo-Spec-FINAL.pdf
In my personal experience 5 years back CGI Edinburgh returned my baby photos with closed eyes, saying Authorities may reject closed eyes photos and asked me to send one's with eyes open for 1 week old baby!
I raised concerns and complaints to Ministry. Over the period of time I have noted they have relaxed the very young childrens photos, below 1 years old.
However whatever the GOI specification and I say. Its your jurisdiction HCI/CGI how they LIKE to deal with this issue is what you will be interested in.
If your travel is not very urgent then I would suggest taking photos as baby is comfortable and then see how it goes. If its urgent then no point taking chance! Just to be BabuProof!!
Good luck and regards.
