According to the doctor’s recommendation. 3 years is a perfect time. You should wait three years before you go for another kid. It would be better for both mother and baby. Th doctors always recommend this thing. You know you should be very careful while choosing your clinic for your maternity. There are clinics that are not good for us. Like my friend has a very bad experience with lotus clinic. I just don’t want to talk about them. Congratulations, and wait for 18 months more then start trying.
