Please Help...BABY CHOKING QUESTION V.I.P.?

I have a 6 week old daughter who I unfortunately will have to put in daycare on october 6th.She is feeding and spits up on occasion due to eating a little more than she needs (according to her Dr) the problem is twice now when she was spitting up she holds her breath and chokes on it & I literally have to pry her mouth open to get the vomit out & get her to breathe. My husband & I are very attentive to her, but I am terrified @ daycare with the divided attention btw the other babies (4) if she does this they may not notice this in time(she is silent when she does it) it something horrible may happen. has anyone elses baby done this- any insight or suggestions will be greatly appreciated. thanks people!!
