i tried to play with him at the daytime when he's 3weeks old, and he can sleep well at night, after formula feeding at 1100pm & wake up at 7am himself; my classmate teached me and it works, & he's now 9 weeks old, it glads to
To conclude, nearly all of our bbs like to 食手指 at this stage. For my case, I try to stop him during daytime or use "紗gun" to block him. I am also afraid whether he can stop 食手指 after I return to work 2 weeks later.
Concerning sleeping at nite, I also agree playing more and sleeping less at daytime will result in better sleep at nite. It is noted that my bb will sleep better if he crys more at daytime or have been 出街 at daytime.
Previously, my bb wake up at 3-4am after meal at 6-7pm and then wake up again at 6:30am. From last nite, I start trying to wake him up and feed him at 11-12pm in order that he could sleep to 6-7am. However, he still wake up at 4:45am and wake up again at 7:00am. I will try to 戒晚奶 by this method.
