Sawai, Rika, & Mew came to see Ayaka after Ayaka had given birth (Sawai had also brought her newborn baby, who's older but still at the same age as Ayaka's baby) - Ayaka's blog entry about it (click the pics to view them in their larger sizes):

^ Sawai visited Ayaka immediately after Ayaka's child was born - no wonder, since they're BFF

- while Rika & Mew, who're also BFF w/ one another, visited Ayaka at a later date. Ayaka also wanna meet Keiko, now a mother of two, soon.
[EDIT]
Ayaka went to see cherry blossoms w/ her child - her earlier blog entry:
