I'm having trouble getting my Peg-Perego stroller to close up for me. It's been a year since I last used it for my nieces and I've pulled it out to use for my grand baby who is 3 mths. old. Can you help me to figure out what is going on with it. I also noticed that when I open it up it wants to fold up so I have to check to make sure it is open completely. I don't know if this may have something to do with it.Thanks ~ Mindy Volney
