Omg so this Thursday my in laws are picking up my two girls(2yr and 3months and 9months almost 10) for the weekend(from Thursday-Sunday) and Ive never been away from them longer then a day. I know it would be good so I can relax and me and my husband can have sometime for ourselves before our new baby girl comes(in 3months). But I'm having super bad anxiety and I'm sad Because I hate being away from my girls and for that many days it's a lot for me plus my in laws live two hours away from us I just worry. I know the more I let them take them the easier it will become but its just hard!!!
