Playing at the Mall

At the mall near my house there is a indoor park made of foam toys. I can take Emma there and she crawls around and "talks" to the other kids. She really likes to play there. She is usually the only one that crawls, although today there were two other children that crawled. The only thing I don't like about going there is when the other parents ask me "How old is she?". I tell them 13 mo and they give me what I call "the look". "The look" is "Oooohhh, she is 13 mo old and STILL cawling?" Every mom who has asked me this question has given me the exact same look. I feel I have to make an excuse or explain that she is more verbal then physical or that its still normal that she is not walking yet. I just wish mothers were not so judgemental. I hope that I am not like this when I am out around other moms. I will still take her there b/c she likes it and it gets me out of the house, but I look forward to when she is walking so I don't have to deal with "the look".
