Hello, I m writing to inquire about a lump that appeared on my daughter s forhead a week after her birth - twin, c-section birth (her brother has no lumps). The lump started as a small red fleck and grew quickly - now is M&M sized, mushy with a red birthmark. She is 10 months old now and acts normal and falling into place with all the milestones - laughs, smiles and doesn t seem to have any pain. I was told not to worry - it would grow and then shrink around age 2 - my pediatrician seems confident as she said it was a collection of vessels. Should I be worried, what should I watch for, and/or are these lumps common with twin births / C-section? Thanks
