Baby moving

So Im 26 weeks (tomorrow), and my baby moves when I'm laying down and very rarely when I'm walking around at work, but the movements are still pretty small. Like it just feels like a tiny poke from inside. Is that normal for as far as I am or should I be feeling and seeing harder and more frequent kicks. My baby was 3 weeks ahead of schedule in growth and weight at my ultrasound 3 weeks ago, so I thought maybe he would be making stronger movements by now. I might just be a paranoid first-time mom!
