Re: Growth spurt?
Welcome to the forum!
I have an aunt who has 6 children. She says "the only thing that is constant about babies is that they change all the time." Seriously, just when you think that you have a great routine and you're on top of this whole mommy thing- that's when your kid will change everything!
A lot of people talk about something called "the 4 month fussies" or the "4 month sleep regression". The fact that there are widely understood terms for this points to how normal it is. No-one really knows why babies in this age range suddenly become so wakeful- is it that they're teething? Rolling? Hungry? Lonely? Is there some fundamental neurodevelopmental shift that's occurring? And because we can't know why 4 month old babies are suddenly waking so much more, it makes the night-waking harder to solve. Often the best thing you can do is to roll with the punch. Don't try to change the baby, just try to rearrange your life so that caring for her is easier. Nurse her on demand. If she is sleeping by herself, bring her into bed with you so that you can nurse and doze at the same time. If she naps during the day, don't take that as an opportunity to do the dishes or sweep the floor or whatever. Force yourself to lie down and close your eyes.
Just FTR, nursing every 1-2 hours is a lot more normal than nursing every 3.5-4. Most babies require a minimum of 8 feedings per day, and many require significantly more nursing sessions than that. My kids nursed every hour or two during the day until they were into their second year.
Coolest thing my big girl said recently: "How can you tell the world is moving when you are standing on it?"
Coolest thing my little girl sang recently: "I love dat one-two pupples!"
