tbh my DD never cared for her Baby Einstein exersaucer.
she did not like being contained in it for some reason and seemed to feel quite claustrophobic when I used to put her in the seat...and would just cry horribly and non-stop. Now that she is 16 months old and very mobile, she will get a kick out of getting in there every once in a while (and ask for it) but it is only for a short period and don't you dare leave her in there alone! Oh ...and for some reason all the lights, animals sounds and bright colors seemed to not only scare her (partic. the sounds) but leave her completely over-stimulated. LOL she looked like a rabid, wild animal foaming at the mouth afterwards (a bit of an exaggeration but she was wild looking fer sure). So really we used the exersaucer more as a pseudo gate to block her from getting to other side of the family room (the other half of the room is her play area).
I would see if a friend or someone you know has an exersaucer they can loan you... and try it a few times and for a period of time (and not just one time as we put DD in an exersaucer at the toy store and she seemed to love it initially)....observe and see if your LO enjoys it. HTH -Good Luck!
