It sounds fine hun, but you could get the Sky, Internet and phone cheaper.
I did go with Sky but I only pay the minimum for the TV package (£18 I think) as I live somewhere where you get next to no signal even with Freeview. I get my phone with them as well because the place I have is new so BT wanted to charge me £125 to 'install' the phone line (which is horrendus that they charge this much when all they have to do is flick a switch), Sky dont charge you to set up the phone line so I saved money that way and also get free broadband with them, pay £11 for my landline rental and have there free option on the Sky phone thing where you get free evening and weekend calls.
Have you thought about a child trust fund as well? I put £20 a month into Brady's so he's got something when he's older. And it's also good to budget some savings every month for things when they're older, like a highchair, stairgate, new clothes, I do it for toys as well as Brady was born in October so there's a big gap between Xmas and his birthday.
