Hi Y.!
My DD is 2.5, and I can't totally remember how much food she was eating at 11 months, but I will do my best! She was nursing 4x/day, and I think we did a 7-8 oz. bottle if we were doing that for a feeding... By 11 months, we were basically at breakfast/lunch/dinner plus a breastmilk feed and maybe snack right before bed. I always nursed her before I fed her table food. She ate at approximately 4-5 hour intervals. Breakfast was typically oatmeal with prunes and yogurt with fruit. Lunch and dinner were combos of protein/fruits and veggies (egg yolks, beans, meat, potatoes, veggies and fruit - some pureed and some not) ...I think we introduced wheat products right around 10-11 months (we waited a little because of family wheat allergies). My guess is that she was having about 32 oz. of breast milk/day, but as others have said - just a guess, since it isn't really measurable. When switching to a cup with milk...hmmm...I remember that she drank water fine from a cup. But when we were switching to cow's ilk, she did NOT want it in a cup OR bottle...she drank it out of a "grown-up" cup with our help. And, eventually, she went ahead and took it out of a cup once she was used to the flavor. Keep trying, or try a different cup? We had to try several sippy cups before we found one she liked (now she'll drink out of anything!) - I think the one she first loved was the Nuby cup.
Sleeping - I was big on having a routine. I was a better mom, and she responded well to routine, too. At 11 months, sleeping was something like...
7ish - up, then breakfast and play
9ish - nap for 1.5-2 hours, then lunch and play
1ish - nap for 1.5-2 hours, then dinner and play
between 7-7:30 was nursing then bedtime...earlier if naps were shorter.
She began to transition to 1 nap shortly after her first birthday. She'd often take a short AM nap, and then sometimes the PM nap was short too! When that started happening more regularly, we started doing a nap more around 11:30 or so, and then gradually moved it to 1:00. It was hard, because if we ran errands in the morning, she'd be starting to fall asleep in the car, and if she snoozed, then the real nap was hard to get...then we were both a little miserable! ;) But, I really worked to keep her busy in those mornings and keep her awake in the car or whatever. And...once she completely transitioned to that one nap, she started sleeping a little later in the morning! :-) I know that doesn't always happen, but since I didn't have the morning nap to "protect", I let her sleep later. that eventually turned into her sleeping between 30 min to an hour later! Even now, if she wakes up and I need to grab a quick shower or something, she's content to play in her bed for a few - in fact, she kind of needs a little "wake-up" time to sing and chat.
Hope that helps a little. If your DD is ready to go to one nap, it's not the easiest transition, but once you're there all the way, it's AWESOME! Much more time blocked out for playdates or other things. You can do it!! :)
