Hi hun,
I don't think its anything to worry about, he'll let you know if he's hungry through the night , no doubt about it :\)
Sophie skipped her bottle couple of times and slept through anyway, I guess its just like with adults, we skipp food sometimes (although I can't remeber mysaelf doing this lately ,lol

)
Maybe you little Gabe fell in love for the very first time and his way to excited to have a bottle ?

lol x
