I recently became an auntie to 4.5 year old and 2 year old siblings. I won't go into details but both birth parents, who are extended family members, died unexpectedly and the children are now under the guardianship of my sister and her husband. Anyway, the children are delightful, but it's been quite a challenge for my sister (who has been ttc for 5 years). I'm concerned about my sister's parenting strategies - her and her husband are rigid about schedules and let the children CIO, they employ "time outs" frequently, etc. I also want to help my daughter, who had been the only grand-daughter, niece, ets. adjust to sharing the attention of grandma and the other relatives and embrace her new cousins rather than feel jealous of them. What kind of resources are available? Is attachment disorder something I should make my sister aware of?
