Growth spurt

Lindsay

My baby has been sleeping more than usual. Her naps are longer & she’s been sleeping 10-12 hours at night as well (waking up to feed every 4-5 hours). She just turned 3 months, 3 days ago.

Could this be a growth spurt??? She used to nap 30-40 mins at a time now it’s been an hour and sometimes 2 hours.

Should I be waking her up? Or let her sleep.

Thanks
