DT1 is in hospital with a chest infection (both DTs have cf) at the moment (probably 2 weeks in total) and they're really struggling with being apart. DT2's behaviour is generally good but she's really challenging DH and they both cry at night about missing their DSis. DT2 can't visit because of infection risk. We've tried exchanging pictures and they FaceTime every day but they're not coping well this time and it hasn't been such a problem in the past.
