ah, i see. ok. however, i still think 2 1/2 weeks is too young to worry about bad habits - agree with scummy that it is a question of being realistic...
gf herself allows for the fact that babies are likely to wake early at this stage. have a look again and you will see there is some guidance on what to do in this instance - iirc she advises that you give a smallish feed, then a full feed later at 7.30am. do have a look again, even gf herself acknowledges that what you are experiencing is perfectly normal for a baby this age.
whatever parenting approach you choose, it's obviously important that you and dh agree on what is best. since your dd is formula fed, of course there's absolutely no reason why he shouldn't get up and do one of these night feeds, so you can get a bit more sleep at night.
don't know what you mean by bulking up the feeds? if you mean thickening with extra formula, please don't! this is not advised and i understand it can be harmful.
so sorry to hear you were so upset this morning. if you were a first time mother, i would say, just chuck the book away, once you are in tears over the routines, things have definitely gone too far! however, the issue here seems to be the fear of a repetition of what happened with your ds. could you talk to someone about this, say your GP or an HV? or maybe other friends with children?
i would still urge you to try not to worry about this for the moment. as you see from ghosty's note, it is possible to introduce the routines later with satisfactory results. it does sound as if they have become more of a burden than a help.
best of luck, agaazaa, and hope things are looking better for you soon.
