My butternut squash had been growing nicely up until about 2 weeks ago. They are quite small (for butternut squash), and have not increased in size for about 2 weeks. Is this normal? I mean, I'm getting lots new squash on the vines, but the two initial fruits have stopped getting bigger. What should I do? (BTW, this is the first time I'm growing butternut squash).

Squash need regular feeding throughout there growing. You can try to fertilize or increase the fertilizer if your all ready doing so.
Also make sure the squash are just not all ready ripe and ready to pick.
Most are mature at 8 to 12 inches, but this can vary with the variety.
Look for the the stem of the squash to turn from green to brown, this will indicate the plant has stopped sending nutrients to the squash.
If you press your fingernail into the flesh it should resist. This indicates it is ready to pick.
I also like to use Epsom Salt on my vegetable plants. This can give them a boost during the heavy growing periods of summer.
