Paula, it really does sound like things are going great! I know how you feel, though, I've done MORE than my share of panicking! Just keep in mind that every day might well be different, and that's okay. Appetite and preferences can change from day to day, so if he changes things up every so often, there's usually nothing to worry about. You're doing fine, just keep an eye on his formula intake (an off day from time to time is okay) and respect his appetite. If you offer solids and he isn't interested, no biggie. Since formula should be his main source of nutrition for a few more months, skipping a solids meal every so often is perfectly fine. The routine may not be identical from day to day, so try to stay flexible and enjoy it!
