The two-hour block will feature popular Nick Jr. shows including 'Dora the Explorer' and 'Thomas the Tank Engine', which are broadcast on Sky Digital.
Until now, pre-school programmes on Freeview have only been screened on non-commercial channels CBBC and CBeebies.
The channel kicks off this week and will run seven days a week from 7am to 9am on family music channel The Music Factory.
