Our 8 month old cat had kittens yesterday...and?

2 survived and are so active, scooting around, making little noises :). Now, we moved her from the birthing box into a bigger box. she was fine laying with them all day yesterday and feeding them. well we went to bed and i woke up at 4 am to check on them and she moved the two kittens to a corner behind the computer desk. it doesnt appear big enough for her to nurse. so i moved them back to the box and she picked them back up and put them in that corner. she lays right next to the corner. is it possible she is feeding them or should i go ahead and get some bottles and milk replacement just incase.
