Hi all! First post here so bear with me. My fiancé (partner of 3 years) has a gorgeous 7 year old girl who has has split custody of with her mum (50/50 split) and recently she has been crying every single night at bedtime. It's taking around 1-2 hours of crying every night to settle her at the moment and it's really taking a toll on all of us, my step-daughter is usually such a happy, cheerful girl and it's horrible to see the impact this is having. We have tried everything under the sun to help her settle, so far calming music and 15 minutes alone before her bedtime story seem to be helping the most but bedtime is still a struggle. Unfortunately, at mum's she shares a bed and mum stays in her bedroom until she is fast asleep every night. Mum lives with her family and is planning on moving out independently, where my step-daughter will have her own room and her own bed eventually but we are not sure when this will happen. My partner and I are trying to do everything we can to encourage a healthy, independent relationship with sleep for step-daughter but nothing seems to be working at the moment. The last time she struggled like this was when I was introduced to her life and it lasted a few months but we worked together and it passed, this period has started up when mum entered a new relationship but unfortunately it has been about 6/7 months now and things seem to be getting worse. It has gone from tears to her being very dysregulated and hyperventialiting. She has a consistent bedtime routine with us but not usually with mum which can make things more complicated. Does anyone have any experience similar to this? We plan on talking to the school nurse after half-term, is this something they could help with? Or the doctor perhaps? There's a lot of other external factors and my step-daughter is very mature for her age, I worry that something serious is going on in her little brain and am just feeling very helpless.
Thanks in advance x
