I'd wait - the guidance is 6 months, it's only a couple of weeks away.
Here are a few extracts from www.kellymom.com on this
"Why delay solids?"
Delaying solids gives baby's digestive system time to mature.
If solids are started before a baby's system is ready to handle them, they are poorly digested and may cause unpleasant reactions (digestive upset, gas, constipation, etc.). Protein digestion is incomplete in infancy. Gastric acid and pepsin are secreted at birth and increase toward adult values over the following 3 to 4 months. The pancreatic enzyme amylase does not reach adequate levels for digestion of starches until around 6 months, and carbohydrate enzymes such as maltase, isomaltase, and sucrase do not reach adult levels until around 7 months. Young infants also have low levels of lipase and bile salts, so fat digestion does not reach adult levels until 6-9 months.
Delaying solids helps to protect baby from future obesity.
The early introduction of solids is associated with increased body fat and weight in childhood. [links to more detail on this, on kellymom page linked to above]
Delaying solids makes starting solids easier.
Babies who start solids later can feed themselves and are not as likely to have allergic reactions to foods.
