Any tips on waking LO gently, but actually getting them to wake up? I love to snuggle a sleepy baby, so I had a hard time making myself wake LO this morning.
(I WAH and had been letting LO sleep in, but she is really getting to bed too late so we are trying to wake earlier per HSHHC).

Re: How do you wake your LO?
its rare that i need to...usually only after a late nap, if i dont want to screw up bedtime or something..
i dont like to wake him 'directly'. so i will open the door to his bedroom, turn off his white noise and/or open up one of his blinds. he usually stirs and wakes after any sort of change to his environment---hes a light sleeper.
if i talk or sing to him to wake him, he will startle, and get grumpy.
DS is a morning person like his momma so I pretty much never need to wake him. Also he wakes super easily so walking in the room would probably do it. Each time I've thought, "oh, I might need to wake him from this nap so that we can go to X," he has woken up on his own so I didn't have to worry about it.
Some advice you'll get would be to let the sunlight in and turn of noise machines/fans/A/C units/etc.
My advice to you is to let him sleep, though. Maybe try to work on the sleep on the other end. I also think that HSHHC is a little strict with its recommendations. When we have tried to conform DS's adequate sleep schedule to the HSHHC recommendations it has not really worked; he has gotten less sleep, there has been more crying, and the night waking has come at an even more inconvenient time than before. We were trying to fix something that wasn't THAT broken and it was just stupid because every child is different...they do not ALL follow the 7pm to 7am pattern.
HSHHC is a great book with a lot of excellent advice, but you should not be too concerned about following it perfectly.
I'm not. We just woke her at 7 over the weekend and naps went a lot better than when we let her sleep in so we're going for that approach now. She goes down for the morning nap MUCH easier if I wake her at 7 than if I let her sleep till 8:30.
I usually only have to do this during long naps when we have somewhere to go. I just come in and softly stroke her back and talk quietly to her. She wakes up fairly quickly. Sometimes if she's really tired it takes a while longer. I don't pick her up though. I think its better if they wake up on their own... well sort of..
She has never cried during this time.
