Skeppers - I felt the same as you! The thing that changed it for me was seeing my baby on a 3d scan at 16 weeks - seeing her feet, hands, face - all so nearly fully formed, seeing her shnuggle up to the cord and placenta trying to get comfy and have a snooze! A few weeks later I started feeling movements (like fishies swishing in my pelvic area!) and slowly those movements became more clear (or so I thought)... I thought I was being punched and kicked, but a later scan showed she was just trying to get comfy and have a snooze! Hard to get mad at that and not blown away by the fact that I already had this baby I was swaying to sleep without realising it!
Right now I am 30 weeks pregnant, and the baby already reacts if I sing to her, she completely reacts to my emotions (as confirmed in hospital when I was on monitoring!) - if I'm scared her heart rate goes up and she goes very quiet movement wise, if she moves around heavily I can stroke my belly and she calms down!
I can see her move and body shape from the outside .. a few weeks ago that would have really freaked me out but somehow, when it's your baby and your body you feel different about it. You will become so protective of him/her - from around 20 weeks I started getting really weird dreams about what I'd do if anyone tries to hurt her!
Without realising it, you're already doing so much to protect your baby - not eating certain foods, or maybe not drinking, protecting your bump area when you are out and about. From 20 weeks things really start to change - I was cynical to start off with .. but your baby will really grow and the way you feel now may be totally different once you start to see outside movement or if you get a 3d scan.
Forget about other people's babies - they are not your baby - they don't look like you, they don't rely on you and you don't necessary love them either! This is your baby, your baby relies 100% on you - he/she was created by you and your husband alone, your body is doing incredible things right now to develop this baby and the next few weeks are going to be pretty tiring but just mind blowing. You go from thinking about 'pregnancy' to OH MY GOD I can see my belly moving and there are elbows, arms and all kinds of baby stuff in there :P HOW DID THAT HAPPEN! And yet if you see someone else's baby, you can still think "Meh!".
And no some people don't love their babies for a really long time - after all babies don't do all sorts of cool stuff, probably will not smile at you for a good few weeks - will tire you out!
But you just have to consider that a baby is not just a baby, they are a person - a tiny little person who 100% relies on you for everything. You are already doing this now without realising it - your body is feeding your baby, protecting them, keeping them warm, giving them a safe place to sleep... :)
You will be looking after this person when they are at their most vulnerable - and the tiny newborn stage is not forever, although I'm sure it will feel like it! Pregnancy is 9 months ... at 9 months old your baby will be more toddler like, and all of my nieces and nephews all had distinctive and loveable traits by that stage.
So in short, don't panic - how your feeling is normal. Most parents I know felt the same, i know i did before i got pregnant and up until the stage you are now. You'll be fine, give yourself a break! And huge congratulations on your pregnancy x
