Morphology
The meaning is directly derivable from combining 'tuck' (to push or fold something into place securely) with the directional particle 'in' (into), yielding the idea of folding bedding inward around someone. This verb+particle composition is a common, transparent pattern in English (and parallels exist in many languages), so a B1 learner who knows the constituents should understand the MWE.
Etymology
Tuck in for bedtime comes from the action of tuck, putting sheets and blankets in around a person so they are snug. That's why tuck in means 'to arrange bedding around someone to prepare them for sleep'.
