Manual breast pump

Hi Mummies, I’m a ftm going to be due soon in 2-3 weeks and looking to breastfeed my baby as much as possible. I understand that for ftm milk supply may kick on slightly later. I read online that colostrum is enough for newborn as their intake is not that much during their first few days. Is it true that in order to collect the colostrum, i must hand express manually using a manual pump because baby won’t be able to suck as it is thick? I already have Spectra S1- i read that it’s not advisable to use an electric pump as it will leads to oversupply right? Any advice from experienced mummies are welcome for me to understand better.. Thank you 😊
