Baby’s height at 3.5 - 4 months

Heya my baby height is 61 at 3 months! But was quite short just one week or 2 weeks before! Suddenly he got a growth spurt and seems like he got taller within a few days and from 30 percentile become 60 percentile! I remember asking my husband if baby seems like taller compared to just 1 day ago, and he also agreed. Monthly checkup proved this to be true! If your LO suddenly seems to be quite hungry, then feed him more. Who knows he might suddenly grow a few cm within days~ If by next checkup he still doesn't grow, then maybe consult with your PD.
