My common law partner of 7 years just left my one year old daughter and I for another woman. I have suggested Joint custody, primary residency with me and he can see her every other weekend and any other days agreed upon. He says that isn't good enough and he wants her every other weekend and twice a week overnight. I feel like she too young to be going back and forth like that.
He doesn't that much time with her now as it is. I know the courts are always looking at whatever is in the best interst of the child, Is she too young for that type of visitation schedule?

Yes she is too young for that messing around... trust a man to only think of himself and what he wants

Is his name on the birth cert?
In ireland unwed fathers have no rights at all - dogs have more rights

This is only a info site so you would have to see a family law pro to go over both parties rights for where your from

No, there is no reason that the court would not give him equal time, one week with you and one week with him. So go with that as a guide that as what he could get as equal, anything less is not equal.

The child is as much his, so he can ask for and normally get this,

Everyother weekend is not much time at all, it is 4 days a month to see your child.
And your "any other day agreed" only means when you say it is OK and will hold that over him to control him. Those days need to be in writing now, so he has asked for "any other day" in what he has asked for and you don't want it.

If he is a good parent then I see no reason why he can't be spending time with your daughter. It is good for a child to spend time with BOTH of their parents. Despite what many people think, men can be just as capable and loving caregivers as mothers. I know you're probably very upset with him under the circumstances, but if you're really thinking about your daughter, you should consider that it's VERY important for her to build a relationship with her father. I don't believe that every-other weekend is enough. Honestly, I think it's no worse than dropping the kid off at daycare at Grandma's during the day and picking her up at night. That's even more bouncing around. So honestly, no, it won't be too hard on her. Providing he does his best, I believe it will benefit her.
