My aunt loves Super Simple Songs on youtube and so does her 2 year old girl. They are both Indonesian and english isn't their first language. My aunt says the songs on this youtube channel has helped my cousin learn English :) and it calms the lil one down when she's fussy. https://m.youtube.com/channel/UCLsooMJoIpl_7ux2jvdPB-Q
