Yes, buy Eu Yan Sang bird nest is the easier and safe. After the 1st Trimester for 1 to 2 months, every morning before breakfast take 1 teaspoon of bird nest.

According to some research, they said if your baby is boy, it is advisable don't take bird nest. If girl, it is ok. Bcos it can reduce the male hormone in the baby. U know what i mean.

Lo Hong Ka also good but u must finish the one bottle within 2 weeks. Quite expensive.

Of course it is better to buy by pieces but it is troublesome to clean the dirt. I also got buy directly from the source instead thru the shops. But i still prefer Eu Yan Shang or Lo Hong Ka.

Some more it is not effective if u eat one or few days only. Must eat everyday morning before breakfast.
