My ex has asked if we can split the summer holidays into 2 so that DS, aged 7, spends 3 weeks straight with each of us. Our court order says we split the holidays evenly, but in 1 and 2 week chunks. 2 weeks already seems a very long time to me! AIBU to say no? I feel my DS already finds the transition back to me hard, even when he has been with his Dad for a week (which he has done in previous holidays). The court order does say we can vary the arrangements by mutual agreement, but I just think DS is still too young for 3 weeks straight away from me. Am I just being clingy? He does spend 3 nights a week with his Dad and we have split previous school holidays equally, so he is used to being with his Dad.
