Thank you, everyone! Yes, DD is almost 3. I seriously don't know where the last 3 years have gone. She is a bright, fun, well-rounded toddler who I swear is smarter and more sociable that anyone in this household. She loves SS and SS loves her immensely; I am so thankful for their bond despite the 10 year age gap. 

I am hoping you all are right and SS will overcome the PAS/GUHCBM childhood he has been raised in with BM and GF and will want a permanent relationship with us into adulthood. I like to think our efforts have been successful despite the minimal time we have him, but only time will tell. I try to minimize expectations to prevent from getting burned in the end. I have had high hopes too often dashed due to a confused/anxious SS and a GUHCBM and GF. BM has still been pulling shenanigans whenever possible (requesting 4 changes to the next 3 months of our CO'd visitation within the last 6 weeks - still prioritizing sports over DH) but DH has done a good job managing her, while ensuring he maintains his CO'd time with SS. End of May 2025 will mark 5 years until he ages out of the court order and CS (but whose counting?)
