Thank you for your query,
Nothing to worry the teething
will happen like this.
As the age grows the remaining teeth will erupt and the space between the teeth will decrease.
Nothing to worry about the space and line of teeth at this point.
They get into alignment as the complete dentition will occur.
Nothing is required at present , but discuss with your Pediatrician
regarding this issue in your child next well child visit.
Hope I have answered your query.
