In general, baby clothing is sized by age. Newborn clothing is marked as NB (for a newborn), infant clothing is marked by month (for example, 0-3M), and toddler clothing is marked by age (for example, 2T for two-year-olds). Buying an adorable baby gown for your baby only to find it too small is a disappointment and a hassle of time and effort to make an exchange. Ensure you buy clothes that fit the baby right. The appropriate size is not only comfortable but also allows the baby to move easily. Babies grow at an amazingly fast rate, be sure to account for growth rate when you are making purchases. Most clothes have standard measurements to guide you if you are unsure of the size that will fit your baby well. However, keep in mind that these are general guidelines, and often, babies fall in between sizes (for example, their height is 3-6 months and weight is 6-9 months).  If you can’t decide on sizes, we always recommend buying the bigger size to compensate for growth spurts. Also, ensure that baby clothes are easy to put on and take off. Between diaper changes, feeding, and burping, the last thing you want are onesies that require a lot of effort to change in and out of. Choose clothes with snaps and/or zippers as opposed to buttons. Again, avoid fanciness and consider practicality. If you are in the stores, try out the snaps and zippers to make sure they are easy to snap on and off or zip on and off.
