Should I buy a manual pump?

maryandmatt

I EBF when I am home with DS and pump while I am at work.  I have a Medela PISA and I am not able to keep up with his feedings but I wake up in the middle of the night to pump to make up the difference.  We are going to Disney when he is turning six months old. Do you think it will be worth it to buy a manual pump to have just in case? (I don't want to lug around the PISA). It might be nice to have a bottle just in case and plus my mom is coming with us so she can take him too. Another reason why I might want to buy a manual pump is because I read that some moms can get more milk using that instead of an electric. That would be so nice! Anybody experience this? Thanks so much for the input!
