I watch my niece 5 days a week sometimes for as much as 9 hours a day. I have tried everything to get her to stop calling me mom (her mom is not in her life nor is her dad). I try to tell her that I'm Aunt M--- but she hears my son (who is only 6 weeks younger than she is) call me mom and she doesn't seem to want to stop. I don't really want her to call me mom but I'm running out of ideas.
Re: Should she call me mom?
It's frustrating. Her mom isn't anywhere that I can tell her and she NEVER sees her mom or her dad. I know the poor kid is confused.
I have 6 nieces so Aunt M--- is not really that special. But the poor girl does have a void that needs to be filled since her parents aren't present in her life.
I do feel bad for her and try to treat her like I treat my own.
How old is she? I run a home daycare and spent most of my working life taking care of children they ALL called me mom for a period of time usually around 14-18 months. They know I am not THEIR mom but mom is just what they have at hand to use. Some children will call all women they know mom briefly before their language develops others use it for a few people.
I have a little one in my daycare right now, 17months, calling me mom. I just try to use my name as much as I can...in time she'll figure it out. I don't make a point of telling the children's mom's that they call me this (as it does hurt) but if the mom's notice I assure them it is a normal developmental process and just encourage that they use my name often for their child to hear.
Unless the child is much older I wouldn't make a big deal and tell her not to call you mom. You'll likely just draw more attention to it and create confusion. If the child is older then the idea of a meaningful nickname might work. Spending 45hrs a day with you makes you a very strong person in her life having a special name can make it all the more meaningful...especially if she doesn't have her mom in her life right now!
ETA: Just saw that she's 2...so it could be what I described above.
