Big baby! in Baby #3

My child is massive! She’s 17 pounds and 24’ long … remember, just 5 short months ago she was only 5 pounds and 18’ long! She’s growing way too quickly and outgrowing everything - I have had to start buying her 12 and 18 month clothes. Still only breastfed - no foods yet other than an attempt at avocado in her mesh feeder (she wasn’t ready and wouldn’t even hold it).
