Hi S.,
There is quite a bit of research out there regarding shared custody and visitation, and my suggestion would be to do some *serious* research and educate yourself thoroughly about the affect it has on a baby your daughter�s age. Get online and go to the library to find good articles, books, and studies.
I know that with older children, the affects depend almost entirely on the quality of the relationship of the parents. Since you have a good relationship with the baby�s dad, then she should adjust well as she gets older. It�s also important to nurture that relationship between her and her father so that the dad won�t loose interest, and will continue to feel connected to his child by spending time with her.
The fact that your baby is so young, and making such a huge and drastic change in her daily life by going from Miami to New Mexico for an extended time period might be something to be concerned about. Talk to a professional, maybe a family counselor, about your options.
I would think that it might be psychologically traumatic for a toddler or preschooler to understand a long term (in their mind) move to another state, to live with another family, with a brand new routine, and to have different clothes, food, sleep schedule, tv shows, etc., without anything or anyone familiar near, and then once she�s adjusted to that, to turn around and send her back to a place and family she no longer considers �home�.
The early research on these types of arrangements 30 years ago said kids were adaptable and could adjust to almost any situation, but more recent research has shown that�s not quite correct. They�re not little adults.
The bottom line is your daughter's well being and her mental state. If she�s too young to understand and adapt to being uprooted and thrust into different living environments, then it may be better to have your ex and his new family come to visit your daughter in her own environment, at least for a few years until she�s older, and able to understand better. You might consider splitting the cost of travel between both families so their burden isn�t as large. Or, visit for shorter periods of time at her father�s *with* her, so that she doesn�t feel entirely abandoned. Or change it up. His family comes to Miami in the summer, and yours goes to NM over Christmas and Spring break. She seems too young to send alone.
I hope this is of some help. Good luck.
