Why is the speaker’s childhood described as ‘a forgotten boredom’?

The autobiographical element makes a reader curious to know about Larkin's childhood. His parents were very loving and affectionate. However, he recalls his childhood as a dejected one. He talks of himself in depreciating terms. It appears that the poet had a very poor concept of himself. It is also known that Philip suffered slight stammer in childhood that endured for the rest of his life, though reduced. If the reader pays attention, argues John Woley, it is not difficult to note the contradiction in the term “forgotten boredom”. If, like Larkin says, he has forgotten his childhood, the question is, how can he comment so confidently that it was a bored one? However, it may be concluded that Larkin's childhood did not have any memories that he was fond of.He even remarked once that his biography could begin when he was 21, which implies that nothing spectacular happened before that. Thus, Philip Larkin recalls his childhood as “a forgotten boredom”.
