How about a few more girly toys such as a basic dolly and pushchair or something which adds on to a toy ds has such as Little People or Happy Street house - these are normally fairly self contained - or collectable books such as Angelina Ballerina or little Miss which won't take up space but will be nice to have later on.
For ds2 we got one big birthday present - a ride on wooden train - I'd had my eye on it for ds1 but thought it too expensive then.
I would imagine you will be inundated with dolls and clothes since you now have a dd. We got lots of books (which tbh we didn't really need) but also a couple fo nice jigsaws and some musical instruments - the latter a good idea as its something they can both do together. Then there are always things they need their 'own' of like soft toys.
I agree with others about just one big present... maybe grandparents could go in with you to buy something really special?
You could suggest to relatives and friends that they put money into a savings account for her... that way you (or her!) can use the money later when it may be more appreciated than on toys.
Could your rellies club together to get a little trike in a girly colour? Maybe one with a "parent's push bar". When my dd turned one she loved a push along dog on wheels; it was big enough to be special, but as i recall it didn't cost a fortune.
