Sorry to say, everyone is right...1st of all, he's only 7 months old, and you're going to go through MANY more changes in sleep schedules, if I were you, I'd be thrilled that he's sleeping from the time you put him down until around 6 at this age! my daughter didn't stop waking me throughout the night (like 2-5 times EVERY night!) until about 4, maybe 5 months ago, and she's 19 months right now. and like your son, her sleeping schedule has also changed for the morning, but not so much the night. with her, the later she goes to bed, the earlier she wakes up (why she does is a mystery to me on that one!) but she usually goes to bed between 7:30-8:30...i prefer the happy medium of 8, but sometimes SHE refuses (and sometimes she's awake IN HER CRIB until about 10) but her normal routine was down at 8, up at 7 (or somewhere near there) now she's STILL going down around 8, but now she's waking up around 5...yeah, that's right 2 hrs earlier! and this started maybe 2, 3 weeks ago...so it had nothing to do with the change of time, most likely, it's the changes going on with the seasons...everything/everyone goes through a change with the changes of seasons. with her, i think it's because it's colder, and her body's wide awake in the morning (colder part of the day for us since his mother refuses to put heat on after she goes to sleep and by morning it's cold in the house) but still...it's the weather (at least i think...for my daughter). but like i said (and another mom) he's only 7 months old, he's going to change his sleeping habits oh so many times before he's set on a schedule. plus,you have to think about it...when the clocks change, it takes a bit for us to adjust to the time change, sometimes it takes us weeks for our bodies to fully get used to the change,it's much harder for a child (especially as young as yours) who doesn't look at the clock to say, "ok, it's only 6am, let me close my eyes until at least 7 before i bother getting up" it just doesn't happen like that. i would try to maybe go to sleep 1 hr earlier to make up for the hr earlier he wakes up. i know, sometimes it's much easier said then done, but sometimes YOU have to adjust around your child's schedule. ESPECIALLY as a SAHM...trust me, while you'll never be too thrilled with the changes in sleeping patterns (unless of course you're lucky enough for him to sleep through perfect times for you to get your rest) but at least you WILL get used to it. as much as i HATE my daughter being up at 5 because that means that my husband is still home, and INSISTS on coming in and talking to me so that i can't even close my eyes again while she sits in her crib for 1-2 hrs watching her dora and diego (or whatever at the moment) i still get up, complain, and take care of her the way i would if she were still getting up around 7/8...just like you will with your son, but after a few more changes, you'll be used to it and most likely by the time he's 1 1/2, you'll accept the fact that you will not have your normal sleep back until he's grown AND OUT OF THE HOUSE LOL...hang in there, it does get better.
