Child PR sponsorship

[Abhi1982]

{{{{{ PLEASE IGNORE/DELETE this post. I posted this here accidentally. I completely forgot I had already posted this query earlier. }}}Hello all, me, my spouse and one child were on PR application and we received our PRs. Later my 2nd child was born. I understand the process is to apply for the child's PR with atleast 1 parent being physically present in Canada.My child is a US citizen. I am aware child can travel without any visa to Canada for 6 months (just with passport). But as we wait for child's PR to be approved, lets say 6 months pass by, what will we need to do as parents? apply for his tourist visa while we all are in Canada? Or is it some other sort of extension he will get (with PR filed) as a US citizen? Also, if someone can please share the process of sponsoring if they have gone through it, many thanks.
