Dealing with engorged breasts in morning

Ca

So my 8 week old has started sleeping longer stretches at night, which is great, but when she does wake up around 4-5 or I am so full that I think it is causing her to have trouble nursing. She squirms a lot, Pops on and off and seems to gulp a lot of air and then ends up spitting up a lot, and is generally very gassy. I am noticing that this does not seem to happen in afternoon or evening feedings - during those feelings she seems to latch on perfectly and will go for 15 to 30 minutes without all the squirming. Any tips for dealing with the morning feedings? Should I pump a few minutes before latching her on? I don't really want to do that at 4 in the morning... should I get a manual pump just to get rid of some of the overactive let down and engorgement before nursing her?
