She won't settle down because she's not getting any real protein and nutrients. She will get some carbs out of the puree but you will find that she will want huge amounts of it to make up for not getting the milk. The few calories she gets in the two ounces over ten hours is being consumed by her effort and stress drinking it sip by sip.

There is no real advice to give that will help. The mom has it set up that she needs her own adult for eating and sleeping yet hired out an adult who has more than one kid. Very very bad parenting. It is most likely working out awesomely at home because the kid is starving and exhausted when she gets home. Mama gets to feed the baby to sleep right when she gets home and puts her down so she can have some serious me time. She most likely gets up mid evening and eats again and then rocked to sleep suckling. Perfect deal-e-o for the mom. She gets to say words and gets handed a kid who has been up all day screaming.

She said the words "do sippy cup" but didn't transition her onto one. She needs to SHOW you the kid can CHUG a sippy cup. She needs to video tape her drinking and sucking continuously on a cup. Have her sit on your couch and SHOW you that the child can easily manage a cup.

She needs to come get the child if she is unable to drink at your house every day. If she goes to noon without taking the cup she needs to come get her for the day and try again the next day.

The baby will be wanting more and more puree because she's hungry and she gets you to do her if you are hand feeding her. That will be what happens next. Stick to normal serving sizes and don't get into the trap of overdoing food to compensate for not drinking.
