The building for infants was constructed later than the other buildings of the Morozov Children's Hospital, which is noticeable in its distinct style and facade design.

The infant department building appeared in 1914 thanks to the funding from Moscow merchant Alexander Korzinkin on the site of the former hospital garden. Its main facade faces the current 1st Dobryninsky Lane. Unlike the other buildings in the complex, this building is designed in a neoclassical style with elements of 'neo-Russian style.' An additional wing was added to it in 1916.

Like the other hospital buildings, the infant department was equipped with electricity, ventilation, and centralized steam heating.

The rear facade of the building, facing inward towards the hospital grounds, is simple and almost devoid of architectural details.

The main facade, facing 1st Dobryninsky Lane, is of particular interest. The central part of the building is covered with a gable roof, forming a triangular pediment. In the center, there are three semicircular windows with semicircular 'eyebrows,' whose arches rest on half-columns with order capitals. On either side of this composition are symmetrical paired vertical windows, above the right one of which decorative plaster ornaments in the form of neoclassical garlands have been preserved.

To the right of this part of the building, there is a one-story extension with four original windows. The right part of the extension features an impressive porch with shortened octagonal columns, which also have order capitals.

The view from the lane is also interesting: the ends of the two-story part of the building in the depth of the site include an attic wall with a parapet and a vertical two-story volume on the left. The left part of the additional wing, connected to the main building by a passage, is also covered with a high gable roof, reminiscent of the neoclassical style. The asymmetric composition of the infant department building is striking.

This building is undoubtedly one of the most original in architectural design within the ensemble of the Morozov Children's Hospital.
