Could share ur baby sleep routine? Trying to sleep train my son. He is almost 8weeks old, waking up to feed once every 2.5-3hours via FM. He cries ferociously each time when he's hungry. How do I stretch his feeds so that he can sleep through the night?

mine started around early 2 months. 830pm wash up 9pm drink milk 930pm zzz and she zz tru the night till morning about 6am for her feed. we follow the time everyday and slowly I guess she just gets use to it. now when it's about time for her milk. she will start rubbing her eyes and then we know we need to wipe her already and then feed her.
