Congrats

Hope you are eating well and taking good care of yourself.

Try, Toys r us, they have a separate section as baby's r us, also mother care is always a safe bet. Center point also has baby stuff.

if you are planning to visit Dubai before the arrival of baby, then you can get much bigger variety and a slightly cheaper then Doha. if you do plan to go to Dubai, let me know will tell u where to shop.

Good Luck and take care of your health
