Ant McPartlin and Declan Donnelly broke their social media silence this morning for the first time since Ant's first child - son Wilder - was born earlier this week.The pair, who share the same social media account, did their first post since the seismic news that the Geordie presenter and his wife Anne-Marie had welcomed a baby boy.The ITV duo appeared on video taking a trip to a primary school, where they have been giving a talk to young children as "Mr Ant and Dec" and shared it to Instagram. However, the pair failed to make reference to the fact Ant, 48, is going to be a regular at primary school soon enough himself after his son Wilder Patrick was born.
