Thank you both for your quick replies.
Sumita - I feel better knowing I didn't have the only baby who wasn't hungry after 4 hours. How long has your baby being going longer than 4 hours? What does your daily routine look like (naps, solid food, etc.), or what did it look like before you had gotten fully on solids? Finding times when Nate is hungry for solids is still a challenge. And he doesn't stay awake for more than 2 hours very easily, so a 5 hour EASY routine doesn't really work. The letters are in a different order morning, noon, and night.
Marie - Thanks for the advice, I will let Nate stay on the 5 hour routine, since he is a healthy happy boy. My husband and I are baffled by our experiences with the dream feed (we've only done it a few times). It seems that the times he has gotten the fourth bottle, or some of the fourth bottle in before bed time, he doesn't need to eat until 6 or 7am, but the times he has a dream feed at around 9:30 or 10pm, he wakes up very early, very hungry. We don't wake him up for it, but even though he is swaddled and in his crib, by the end of the bottle he is a little awake, but goes right back to sleep. If he'll take it sometimes, can I give him more than 8oz at a time to try to get in all his ounces during the 3 day bottles, then he won't need a fourth bottle?
And should I just keep offering him solids at our breakfast, lunch, and dinner times until he gets the hang of it, or keep experimenting with times I offer it to him?
Thank you so much!
