In my stored procedure Im using cte for recursion of date but for few date Im having some problem

This is my query

SQL

Declare @date datetime ='2012-01-30'
;with cte as(
select 1 Nos,@date MyDate
union all
select Nos+1,dateadd(mm,1,MyDate)MyDate from cte where Nos<12
)
select * from cte

If i gave @date='2012-01-25'

CSS

Nos MyDate
1   2012-01-25 
2   2012-02-25 
3   2012-03-25 ...

The iteration is correct. But for @date='2012-01-30' The output will be

CSS

Nos MyDate
1   2012-01-30 
2   2012-02-29 
3   2012-03-29 ...

For march it continues with '29' but i want '30' for march
