I have to agree ... this is DD's responsibility.
I'm from a big family and continued to work after my children were born. I paid for good daycare. One of my sisters, however, continued to sponge off family members for daycare.
Basically she is a user.
Her kids are now older so don't need daycare. Even though my dad has only months to live, this sister only goes to visit them when she needs something. Others, like myself, visit regularly knowing that time is short.
If you can help without jepardizing your job, go for it - however, it is time for DD to grow up and manage her own affairs without Mama coming to the rescue.
