My baby also ee rr around 7AM-8AM...
i tried to ng ng with her..then after ng ng..she drink milk..she fall in sleep again ar la..so i think your baby want to ng ng that time....
dont' wake her up drink milk at night...bcoz she will wake up at that time in everynight....when my baby around 1 month old, she can sleep thought to 6am, then drink milk...but one day i scare she hungry so wake her up at 2am to drink milk, (she sleep around 10PM everynight), from that day she wake up at 2am on time everynight until now. She is 3.5 month now i also don't want wake up at night but i don't know how to stop her.. i tried that so now i need wake up everynight. i better say to you....if your baby sleep through the whole night let she/he do it....don't wake her/him up, if they felt hungry they will wake up and call you..so dont' worry too much..
