K.C.
Went through that when I traveled to Los Angeles to see my husband's family when my son was 6 months old. The entire week was a nightmare. He was so unhappy, wouldn't nap, would take hours to fall asleep, hardly wanted his milk. The whole trip was awful. Not to mention they probably thought I had the fussiest worst baby ever. The only thing that helped was to take him out..to the beach, for walks, etc. He just hated being in their house. The day we got back to our house it's like he let out a sigh of relief. Scoped out his room, smiled at his crib and just was back to his old self. Amazing what babies know. He was home and at peace again.
