This paper presents the submission by the HeiMorph team to the SIGMORPHON 2022 task 2 of Morphological Acquisition Trajectories.Across all experimental conditions, we have found no evidence for the so-called Ushaped development trajectory.Our submitted systems achieve an average test accuracies of 55.5% on Arabic, 67% on German and 73.38% on English.We found that, bigram hallucination provides better inferences only for English and Arabic and only when the number of hallucinations remains low.
