We went to the Maldives in March, DD spent her 1st birthday there. Went to Bandos - may have even been mumoverseas who suggested it!
Bandos is a v short transfer and geared up for babies.
The cot they provided was a proper full sized cot with proper mattress and linen, they have high chairs in all the restaurants. There is a baby pool as well as a big pool - both are good for 11/12mo babies. They have a creche, we didnt use but it was there if you wanted to use it.
We went full board and DD does BLW so the buffet was perfect. We got a bit bored of it, but she loved walking around choosing food to eat. There is the 24hr restaurant there so you can always get milk/food if you need.
DP went diving and he said it was quite well run. The spa is quite good (massages, I'd give the facials a miss).
If you fly with Sri Lankan they do non-stop flights into Male from Heathrow and they are pretty baby friendly.
The thing that annoyed the hell out of us was that the room we had was joined onto another, not detached. There was a family of 4 next door who were noisy, but I am sure that DD screaming at 4am annoyed them as well!
