Just needing to vent

Any one feel their husbands favorite 1 kid? When we got married I came with a 4 year old, and he came with a 2 year old and a 10 month old. It seems like he ALWAYS doing stuff with only his 2 year old. Last night while even having contractions for 2 days he decided to leave me alone with our 4 year old and 10 month old while he took only the 2 year old with his mother to go look at Christmas lights and go Christmas decorating shopping.... It just always seems he chooses to do stuff with only his 2 year old and never the other 2...
