So my baby has a mosquito bite size lump on her head. I've never felt it there but my bf thinks it's been there for awhile...well I asked the doc && her first guess was a cyst or where the bones in that soft spot could be coming together. Suggested we monitor it...but hearing "cyst" struck fear in my ❤. Not tryna have negative thoughts but the thought of losing one of mine is UNBAREABLE!!!!!!😭😭😭😭😭 Especially my Zih...my baby girl just has a hold on my heart tighter than anything! Positive thought && prayers requested.
