The present invention provides an intelligent mother-and-child suit and a nursing method suitable for baby care. The intelligent mother-and-child suit suitable for the baby care comprises a first suitfor acquiring maternal information and a second suit for simulating the maternal information. A first microcontroller in the first suit conduct a pre-processing operation of filtering data in a firstdata storage module, and a second microcontroller constructs an expression database according to collected baby images, performs convolutional neural network training based on the expression database, and trains a baby expression classifier in different maternal situations; and a second microprocessor in the second suit analyzes and compares the acquired baby images with preset baby expressions stored in a second data storage module to determine baby's moods and adjusts regeneration values of each mechanism in a maternal information regeneration module in real time. The intelligent mother-and-child suit can still provide a preferred environment for babies when parents are not around, completely simulates a feeling of being embraced by mothers for the babies, and better cares and comfortsthe babies in all aspects.
