I know an British family who had a son born in the US while they were teaching at a US university. They went back to the UK for good after 3 years in the US, the child did not have a UK passport and they were asked by the IO how long the "American child" is going to be in the UK. When they told him they were coming back for good, they were told to wait. A supervisor came to talk to them, told them that he can not let the child into the UK if he is staying for good as he is a US citizen and not registered as British yet but can give him entry clearance for six months if he is coming in for a short stay. He asked them again how long the "American child" is going to be in the UK. They got the message and said it is going to be a few months. He let them in and told them to get British passport for the child as soon as possible so that he will not have any restrictions on his stay in the UK.
IF a parent was born or naturalised in the UK, then the child is of course British from the moment of birth, but Immigration officials at the port of entry are not trained to make nationality determinations.
Even if the child was born in the UK, those born in Britain since 1983 are not automatically British.
Also - an airline might not be willing to allow a non-British/EEA/Swiss child to travel to the UK on a one-way ticket.
