Baby not taking milk

Da

Today was the first time my partner put baby for a nap and tried to give her pumped milk. He was able to get her to fall asleep after 30 mins of crying but she wouldn’t take the milk... although I’m not sure how hard he tried as he didn’t even do her nap routine prior. Then when she woke up she didn’t really want to nurse either. I know she’s 1 and doesn’t technically need the milk but I’m worried this will make her go through a nursing strike and I’m so upset. I just want my baby to take the pumped milk or at least nurse afterwards... I need some advice or reassurance or something.
