Has your cherubs tripled his/her birth weight and grown 10” in length since birth?

Lala

Went for LO immunization last week only to be told that my LO needs to gain more. I know that her weight and height gain has slowed a bit this month because she’s teething and often screams during meals/milk time. I am now worried cause she now needs to gain about 1 kg (2.2 pound) and 3cm (1.2inches) in height for the next month or so. Anyone else on the same boat? Any tips or advice is appreciated.
