Wow! You truly are a great coparent. I empathize with how you are feeling. I cannot relate personally, but can imagine that it is an uncomfortable situation. My DH has a 9 yo son who was born when he was a teenager. He and BM didn't last much past the birth of their baby. While they were together, they always did things as a "family." Well after they broke up, BM wouldn't allow DH to take the baby on his own. DH asked many times and she pulled back with each request. I won't go into all of the details, since this post is about you, but things are different now of course. My opinion is that he may be a bit nervous to ask that so soon. Even if he isn't 100% "ready", who is when a baby is born. Parenting is a learning experience that happens along the way. He needs to be able to have quality alone time with her in which he can learn his parenting style and not just his "play and have a good time style." So since things are going well, I would suggest that you ask him yourself to take her on his own. He probably doesn't want to push you away. Many single moms do not react well to Dad wanting time with his child after that amount of time. I am sure he has heard horror stories and just wants to make sure that the 2 of you can be civil. For my DH, if he didn't want a total war with BM, that meant he had to see his son on her terms in her home for a very long time. It still is a challenge even 8 years later. Both are married. She has more children, yet she still hangs on to controlling DH by using their son. You on the other hand seem to be very logical and willing to work with Dad and that is to be commended. May I suggest that during his next visit you say that you want his time with your daughter to move from fun visits to real parenting time. Depending on your schedules for work and such, he could start with a few hours in his home 3 days a week. But a word of caution--this opens up a whole new can of worms for the 3 of you. His parenting may be different from yours. He may then want overnights and a very regular frequent parenting schedule. Your daughter could whine to you about how Daddy says no for certain things or let's her do this and you don't. You have to always remember that you are speaking to a child and only find out information through her dad. Something to keep in mind for the very near future is to keep a parenting log that goes between the homes. You 2 can decided what you record in it. Nap times, snacks, meal times, bedtimes, bathtimes, tantrums, whatever. That way you have another format in which to communicate when life becomes real and the stresses of parenting, work, relationships, etc, get in the way. Also, agree upon the major things before she does go with him (bedtimes, # of snacks per day, discipline procedure, etc) She will feel comfortable and familiar with a similar (not identical) routine and expectations in her home at Dad's. Fun visits are just that-fun. Real parenting is rewarding, but you know that a child can go from smiles to meltdowns in about 60 seconds and even as young as your daughter is, she will learn quickly the ways of manipulating situations in her favor when she has two homes. The #1 way to prevent that is open communication which it seems you 2 are doing well at. Good luck and keep us updated!!!
