Im gonna guess and completely speculate that there might not even be a shortage but perhaps just a surge of demand from normal now that most lockdowns have ended and people have their incomes back. Thus all the babies that might have been born during 20 and 21 were delayed and are now all getting a mini baby boom in 22. Causing a shortage, that and it makes a great headline and fear, for people to run to the government to ask the government to solve yet another non problem.
