It is common for babies to be fussy and to want to go to the breast more often at somewhere around this age.  A number of ideas and "names" for this stage have been suggested, none of them based on evidence - terms such as "appetite increase", "wonder week".  The most relevant question is: What has been happening in the last few days?

 

The consistent factor that I have found is that this is when mothers and their babies have several appointments.  These are their 6-week check-ups with the paediatrician and the obstetrician, and they may have an appointment with the Child Health clinic also. These appointments often involve finding parking and then waiting round.  While out for the day, they may stop off to get a load of much-needed groceries on the way home.

 

Consequently, a feed or two is delayed or missed.  The baby KNOWS what to do to make up for this reduction in intake, and wants to feed more often. More frequent feeding stimulates the breasts to make more milk (as the more milk taken out, the more that will be made).  In a short time, if the baby is given unrestricted access to the breast, the slight reduction in supply is fixed.  Easily fixed.  The baby becomes content again.
