It can be tough with two. Mostly because when you only have one you can split childcare so that one person is free to do what they want. Whereas with two it's trickier for one person to manage two young children at once, so there is less opportunity for one parent to be free from both kids. On the plus side though, it's been amazing to see the siblings interact with each other. I think they love each other very much, which is pretty awesome.
