Alice, they're struggling for light. Do you have a desk lamp or similar with a bright-ish bulb? I have a couple that I use for seedlings in the depths of winter. Lower the lamp - or raise the seedlings - till the plants are about two inches from the light. They won't burn. Apart from light, the bulb also provides warmth. Raise the lamp - or lower the seedlings - as the plants grow, always keeping them about two inches from the light.
Don't leave them under the light 24/7. Even seedlings need their night time. 12-14 hours out of 24 will be enough.
