Hi, if it's any consolation, I have the same situation with my son. He's 6.5 months and goes to bed at 6.30pm and wakes between 5-5.30am. I feed him, cos he'll scram the house down otherwise, then put him back to bed until about 7am. He often wakes just before that. If not, I've just started setting my alarm to get him up at 7am.
Unfortunately after finally sleeping thru the whole night without waking for a few nights, he's just gone back to waking about 3am for a feed.
If only I could eliminate that again. I would love for him to sleep until at least 6am, but I"m not sure when / if that will happen.
So, I can't offer advice, but yes, others are out there doing the same.
