Any tips on how to sleep train

Keep the house well lit during the day and no naps after 6pm

Ok I’ll try it. Thanks.. she hardly sleeps at all during the day.. and wakes up like crazy during the night

I have two boys 2&3 and it don’t matter if they go to bed on time 9 pm they back up at 1am til like 7 or 8 am. Then sleep til like 3 pm.

I be thinking because they wake up at that time they should stay sleep when they go to sleep tonight. But this is every night 😫😫
