They get on great but that could change soon as my toddler is starting to reach that "everything is mine" stage!! We just have to remind DS1 that he is only a baby and sometimes they do things differently to communicate. I was a little worried as DS1 has some behaivoural issues and it was a concern that having a new baby around might make things worse but I can honestly say it has actually improved! I think he likes the responisibility of being the "big" brother and having someone look up to him. They play really well and DS2 loves to copy things thas DS1 does. I do wonder though how things will be when DS1 becomes a teenager but then when they are older, as in grown men, I don't think the age difference will matter at all, especially with them both being males.
As far a the impact financially I don't think it has made too much of a difference. Of course we have the added costs of a baby but I like that I don't have two lots of everything to buy if I was to say have two children in nappies. DS1 does three outside of school activities as well and I don't think I would be able to afford that for two.
Hope that made sense and helps!
