My DS went through a phase like this, down to screaming at Daddy to go away and get mummy. It lasted 6-ish months I think (not 100% of the time during the day, but always at bedtime and during the night). What a relief now that sometimes he yells at me to go away
It's probably because she's teething & sick and just needs her mummy. Perhaps once things settle down again she'll want to spend mroe time with daddy again. Make sure you talk about it with your DP and see he understands it isn't really about him. She'll be a daddy's girl again soon.
