Re: looking at signs, developmental issues
If this helps I use to be a preschool teacher for 20+ years, plus have been around many small children and toddlers whose parents are Bi Lingual sometimes the child can get a little confused with the language , and either mix both languages together or learn to speak the dominate language spoken at home or what she has learne the most. this is not common at all. At her age she will have separation anxiety big time going to preschool at first. It will be really hard for her becaue she will not be sure if she will see mom or dad again, it is a scary experience for some toddlers. So be strong , otherwise their are mommy and me classes you might want to look into or something like Gymbree , where the parent gets to participate with the child while meetimg other children the same age and parents, just something to think about because you have some choices .
