Hi all, would really value an unbiased take on this because I feel very confused. I coparent a child with my ex. His Dad has him 2 or 3 nights a week and then he is with me the remainder of the time or at nursery (22 months.) Today I got home from handover and realised my ex partner hadn't packed the thermometer I'd leant him or the ibroprophen for kids I had packed the previous evening. Our child has been ill for weeks following repeated UTIs and being resistant to some strains of antibiotics. He needs the baby ibroprophen to bring his high fever down and ofc the thermometer to test it. My ex just parked up the pram, said goodby to my son and left the handover spot. He skipped any handover info exchange despite me asking if he had had lunch and my ex just walked off before I had a chance to ask about the meds or thermometer. His house is just streets away from ours so after trying and trying to reach him by phone/text/email ANY way I could think of I just went to his house and politely knocked on the door. I needed the health stuff to keep my son below high fever threshold. Anyway, when I knocked it was like be saw red. Told me he was calling the police that I must GET AWAY from his space. It was quite bizarre!! I'd understand if I had a really track record of going there but I have literally only picked up my son from there a grand total of twice in 6 months. Instead honouring his dads request to meet for handovers at the local community centre. Anyway, I'm now worried sick. Could I get into trouble with police for so called "harassment" even though I knocked briefly and politely and asked him about the thermometer. I just needed him not to go AWOL on an afternoon when our son is ill.. any takes? Thanks lovely folk of Mumsnet
