H1B Visa Interview should take wife and Kid?

[naman]

Hi,

I am planning to go for H1B visa interview in couple of week at chennai. We have 6 months old kid.

Please let me know which of the options below seems better, also provide pro/cons for both scenario:

1. Considering problems taking infant along interview, we are planning to go one by one (me first) and drop my kid's application in dropbox for stamping.

2. I take my wife and son together for interview. In this case, any baby food is allowed in visa office? or Any priority treatment?

Thanks in Advance...
