I’m just playing through Majora’s Mask (2Ship2Harkinian) after going through Ocarina (Ship of Harkinian) and the quality of life improvements those versions offer while staying true to the originals are really huge for me. Free camera control, quick actions for things like tunics and boots, d-pad item assignments, HD texture packs, etc. Highly recommend it for anyone who likes the games, I usually replay them once a year for nostalgic reasons, I will always use these versions moving forward for that now.
Sleep training like that is a bit extreme imo, we started with a much lower threshold (5 mins) and only expanded a little bit (+5-10 mins) until our kids started to adjust. Worked well enough for them, they were sleeping mostly uninterrupted regularly around 4-5 months. Some regressions happen but we just apply the same technique and they’re back to regular in a couple days.
