Ran out of birthday gift ideas for 5 year old boy and 7 year old girl

We've always wanted to make every birthday gift extra special and memorable for the kids because usually we don't do have a party for them. So the main gift comes from us. I think so far we have because they remember each of their birthday gifts quite well (because we constantly remind them). lol. However, we're beggining to run out of ideas! The going to be 5 year old boy's birthday is next week and the going to be 7 year old girl's birthday is next month.

So far for each of their birthdays we have got them the following gifts.

For the boy

1st birthday - A rocking horse (I remember looking really hard for this one. We had seen it earlier and really like it but then we waited and when it was close to his birthday, it ran out of stock! So we went all over to search for it.)
2nd birthday - A stuffed toy dog (He really liked this one too but then later on he had rashes and the paeditrician told us to keep away any stuffed toys and so the poor toy door sits in an empty drawer till now. I guess thats why the kids still love it so much.... because of the fact that its forbidden.)
3rd birthday - A motorized bike. (He loves this one very very much till now.)
4th birthday - A lego duplo toy set (He didn't seem to like this one very much but last night he took it out and fixed everything himself by looking at the pictures and he seemed to have a good time playing with it. Maybe it wasn't age appropriate for him then but it is now.)

For the girl

1st birthday - A push toy that can be converted into a car that is "driven" by pushing the legs on the floor. (The kids still like to sit on this "Car" and "drive" it around once in a while.)
2nd birthday - A toy laptop (This is the lousiest gift of all. It didn't work very well after a while. She still asks for a toy laptop every now and then at the toy shop but each time we would remind her of this lousy one she had.)
3rd birthday - A musical keyboard (This is lovely and a good start for introducing music in a child's life. I still remember on her birthday she wore a cute denim shorts with sunglasses and she rocked by singing on the mike that came with the keyboard and dancing to the preset music. She looked so cute then. Oh, how fast the time has flown.)
4th birthday - A pop up house (Definitely a hit with the kids. They still pester me to open up their pop up house once in a while to play with it.)
5th birthday - A tv console game (She didn't like this at first but liked it later on after she learned how to play. We have since added on some new games for them which they enjoy occassionally eg on a Saturday morning when mummy wants to sleep in and daddy wants to play his pc game.)
6th birthday - A white board on an easel (This is a wonderful tool which we use now to teach the kids their school lessons. The kids love to write on it too. I guess it makes them feel like a teacher.)

Every gift has been special with its own set of memories and we hope to continue the tradition.

Every child is special and has different preferences but feel free to borrow my birthday gift ideas above if you like.

Does anyone have any good birthday gift ideas for a 5 year old boy and a 7 year old girl?
