Might be leap or colic. If its leap then its normal. Just keep comforting baby. If colic Maybe u can try applying some oil on baby's tummy before bed and during every diaper change. Do some massage on baby's leg too. Some use telon oil , some ppl use ruyi. I use telon oil cos ruyi too hot for my baby. Or alternative u can try give gripe water. When my baby was 2m i only gave 2.5ml (even though description put 5ml)
She could be going through a leap. You can download Wonder Weeks app for more info about leaps. To help her sleep better, try to keep a consistent schedule, keep the room cool and try to switch on white noise
Colic? Diaper? Too warm or too hot? Too bright or too dark? Try hug baby close to your heart when she cry, our baby also like this when she was younger.
Update: LO was cranky and fussing alot as per my post for those 2 nights and things are back to normal now. It could be leap, thanks for the idea!
Most likely colic or gassy stomach. It's very common in newborn as their stomach is still not mature
Colic or reflux. Is it after feeding? Did Lo try to kick backwards
Colic ? Try some grip water
