Combined & confused

So today we combined the litters from Vanilla and Little.  Both mothers are fine with being around each other but of course Little is totally confused.  She keeps heading down the hall and just sitting in the empty pool still in my bedroom.  Now she has resigned to sitting with the bunch and Vanilla is not having any interest in being with the puppies.  She may change her mind when she's away from them for a while and fills with milk!
