Separation Anxiety

I have been hearing a lot of this since a lot of my friends' babies has reached this phase. I'm not an expert here but from what I observe so far, it's the sense of insecurity when toddlers are separated from their loved ones and in some cases will lead to non-stop wailing. It could even become a serious psychological condition if it's not handled well. I've realised that even adults can suffer from it. JQ has a very cute cheeky adorable niece who is almost 2 years old now. As she is the first baby in the family, all of us really dotes on her. Most family days will be spent going to places that the baby and all of us will enjoy, like going to parks with playgrounds, beach, or just dinner or mahjong at home. Whichever the activity is, a lot of attention will be on the baby as most of us sees her only once or twice a week and will spend the quality time playing with her, esp JQ and Nance. Her caregiver is her grandma, aka my MIL. She takes care of baby Enya during the day and will come home when the parents are back. As this is her first grandchild, she definitely loves her a lot as well. The baby used to be quite sticky with Ah Ma and will always look for her. However recently, realised that there has been a trend that Enya will recognise playing companions, so everytime when we go out, or when the whole family gets together, she does not want Ah Ma anymore, as in don't want her to carry, won't look for her to play. Preference will always be JQ or Nance. Can totally feel her "sense of insecurity" when that happens. Wonder if this is the phase that most grandparents will go through... hmmm... ??!?
