I do not have littermates but my girls are 6 weeks apart in age... Athena is now almost 7 mos. and Eden is almost 5.5 mos... It will be tiring at times but it does get easier I promise.
Athena d.o.b. 02/01/2014
Eden d.o.b. 03/15/2014
There comes a time when you have to choose between turning the page or closing the book.
