I do that too, I'm pretty sure as we get closer to the new arrival our LO's will be a little wiser and easier to deal with.
Sometimes I feel like I can't cope with one let alone two but that's normally when I'm really tired ie most of the time right now lol
in my heart of hearts I know it'll be ok but very tough for a while, we've had so much thrown at us this year with bereavement, moving house, redundancy, DHs business going bust and me being in a major car accident that I'm pretty sure we'll cope just fine with another baby.
When I see a newborn I go all goey but I'm sure that'll change as the pregnancy progresses.
Feeling much more positive today and not as sick, caught up on a bit of sleep last night too so feeling more human again.
