Hi, I really feel for your DP, so disheartening when your child doesnt want to be near you....I dont have an answer but I know my 2 of my neices were exactly the same - for a few months they didnt want anything to do with males, including daddy, uncles or poppy! The only time they could get cuddles is if they had food lol...but the phase did pass in a couple of months and now they adore all males - to the extent of if they have a choice the male will win hands down everytime now. It is weird but I guess just another one of their phases...
