My 1 year old baby's 2 front teeth has a huge gap in the middle. Is it normal?

It's normal for some kids. Maaayos pa naman ang spacing nyan once tumubo pa ung ibang teeth and milk teeth pa lang naman yan so it's not the permanent alignment/spacing of your child's teeth.

It will eventually close when other teeth erupt. But that will happen after 2 years.

Yes it's perfectly normal. Once more tooths erupts, it will be joined together
