First weekend away

My husband and I have a ski trip planned next weekend. Leaving Friday morning and returning Sunday mid-day. He will be staying at our house with his grandmas. I am a stay at home mom so the longest I have been away from him is about 8 hours (2x). I am freaking out about leaving him for this weekend. Is it too soon to do this? He will be 7.5 months. Or do I just need to relax and do it?
