I have a 11 month old lil girl. How can I tell if she is constipated?? She always goes at 5 every night for me but in the last 2 days she hasn't gone. I ask other members of the family if they have seen her go but of course I don't think anyone pays any attention. So I'm really not sure.

She is active and doesn't seem to be sluggish. Please help.
Thanks.
