Alyson Hannigan

Make way for another mother on How I Met Your Mother.

Cobie Smulders is pregnant and due in the spring with her first child, People reports. Dad is her boyfriend, actor Taran Killam, better known as Barney’s abrasive former co-worker Blauman on the CBS show.

The actress’ joyful news comes one month after Alyson Hannigan announced she is with-child, which poses another baby pickle for the sitcom’s producers: Will Smulders’ pregnancy be written in?

If it is, it may be a surprise pregnancy, as Smulders’ Robin has vowed never to have children and it has been implied that she doesn’t. Thus far, Hannigan’s pregnancy has not been incorporated.

What do you think? Should Mother write in either pregnancy? Could Robin have a change of heart and have kids?
