Nilagnat po si baby kahapon then ngayon po may sipon siya

Ay, normal lang yan, mama! Pag may lagnat at sipon, madalas talaga na nahihilo at pagod ang babies kaya mas matulog siya, it's their body's way of fighting off the virus, pero good sign na masigla pa rin siya pag gumigising, meaning she's still her usual self naman. Just keep an eye on her hydration, make sure she's feeding well, at kung tumatagal pa rin or may ibang symptoms, better check with your pedia to be sure, pero from what you're describing it sounds like she's managing okay.
