Mnemonic

A child dons a ceremonial hat and tilts her head back, opening her mouth wide to receive heavenly blessings raining down. The hat funnels each golden drop straight into her mouth, and the child gratefully savors every gift bestowed from above.
Additional thoughts
Picture the hat as a funnel shape on top, the mouth open beneath it, and the child as the humble recipient — the structure of the kanji stacks exactly this way: hat on top, mouth in the middle, child at the bottom.
Quick recall
A child in a hat opens her mouth to receive blessings from above.
