Re: How not to compare twins' development?
Totally normal Mama! And in some ways it is good. You are closely aware of what each one is doing so you can watch for red flags, etc. Mine are developing about a month apart in gross motor skills...but I honestly think it is a large part because 'A's personality is just more laid back (she has been more content since birth).
Mama to DD 10, DD 8, DS 7, DS 5, and identical twin almost 1 year old girls born at 26 1/2 weeks and doing super!
Thanking God every day for our blessings!!!
