hi momsh! 👋😊 15mos old na din bby ko😊 same experience... minsan super late na nga matulog😅 i'd suggest keep a routine na dapat by ganitong oras sleep na... dim mo na yung lights, tapos medyo palamigin mo yung room😊 kung ayaw pa talaga matulog, read kayo ng book😊 or any quiet activity kahit saglit lang... then higa na kayo to encourage sleep time😊
