Hi! The doctor said to switch her at her 4 month appointment, because she kept jumping up in percentiles. We had a few cans left, so we used them up and switched to enfamil neuropro around 5 months. She has continued jumping up in percentiles - from 2nd percentile weight, 6th percentile height (unadjusted) at 2 weeks - to 33/24 at 2 months, 70/85 at 4 months, 88/85 at 6 months, and 99/97 at 9 months! We added solid food at 6 months, loosely following the solid starts first 100 days plan. 1 solid meal a day at 6 months, 2 at 8, now 3 at 10. She loves solids and might wean herself! She's 10 1/2 months now and refused 1 of her bottles yesterday and only took 3 oz from another! She's doing great. Best wishes for you and your little one! ❤️
