Seconds - I hear you! I'm often alternating between feeling frustrated with the long days and how relentless looking after small people can be, and awareness that this is a really special time that I want to make the most of. I think it's completely normal to value different elements of your life too.
Clarella - I agree, if G needs feeding at night then feed him. I know some people would disagree but I reckon any sort of sleep training now will just lead to frustration all round.
I think someone mentioned a couple of days ago about their LO suddenly getting very upset for no apparent reason. N started it yesterday - sat in his bouncer quite happily then started shouting in a really distressed way. Thought at first he was in pain (teeth again maybe?) but was fine and smiling the second he was picked up. Unfortunately it carried on into the night - would put him down in his crib and he'd very quickly start shouting and giving me the most indignant look. Ended up co-sleeping all night as a result.
Think he might be having a bit of a developmental leap and therefore just needs reassurance - he seems to be making concerted efforts to role now, whereas I think it was just fluke really when he did it before.
