@Turquoisesol our pup doesn't like strokes either (have to wait until he's sleepy to get a stroke or when he is eating from a bowl weirdly enough). Like previous people have said it is linked to timing and area. E.g. as a person, I would be annoyed if someone stroked me on the head when on a conference call but may enjoy a massage when chilling. I am also hoping when morningpups mellow with age into an adult lab he will love them. Sorry this doesn't help much but know you're not alone with 'no petting' pup
Ours bites during witching hour and in non-witching hour will occasionally lick my partners legs (often when sleepy). We used the impromptu licks to start teaching 'Kisses'. We are hoping the combination of leaving him in the pen when he bites and rewarding kisses, he will pick up on we prefer a kiss (!?)
I would also like to learn gentle and didn't think of it until I read it here, as some times when he takes a treat he gets my hand instead 
@CleverQuacks I am sorry I don't know much about this but hope to have 2 dogs after morningpup get to 1 year old +. My gut tells me that it will take time and it is early days yet. My sister hated me when I was born and did try to get rid of me
Like a younger sibling, your pup suddenly has to share your attention and put up with a yappy/silly puppy. If you feel really low and only if you can afford it, I would seek a 1-2-1 trainer/behaviourist who has dealt with this to come round. Sometimes having someone who has seen it 1000x times before gives you reassurance and confidence to break through puppy blues. However this has a cost attached and I would only do it if I could afford/budgeted for it (particularly as we are easing towards payday and I know my budget has gone on hidden puppy costs!).
@tizwozliz it is isn't it
albeit pretty sure mine is up more than 5 hours
