Yes, I did mention the reason for uploading baby doc's in LOE section.Well I do not know why many applicants reported here that they were not able to make changes in their EE profile before getting the document upload page.As far as I remember it usually ask before accepting the ITA..
So like you said baby get born before submission and you were not able to change in your Profile but you did upload some documents for your baby, I have couple of more question-
1- Did you mention the reason in Letter of Explanation that you are not able to upload baby documents and unable to make changes in your profile
2- Did you submit your Proof of funds considering your new family size.
3- What documents you did upload , did you upload baby's passport and birth certificate ?
