Hi Randomcitizen and welcome to the forum;
We have one other member with a similar case; hopefully she is lurking and will share her experience.
But you are correct it is still under the family class sponsorship and in previous years dependent children did get priority at the Kingston office but so far based on what you will read on the forum; there seems to be a major back log.
I pray your case be processed soon; as your child is very young.
If you are interested you could share your timeline and my self or chickie72 can add you to a spreadsheet
that we manage processing timelines on. The link to the spreadsheet is found under either one of our signatures.
All the best
