If your on ur company's sponsorship, then what u need is a certfied document done at ur embassy where ur husband certfies that he gives u full guardianship of the child and an NOC from him (ur husband) then those documents are submited and u can sponsor ur child. .. it will not be hard especially that ur child is under 1 yr of age.

speaking from experience as i have a relative who has done it.
