Congrats Sandy22! How exciting for you! Madison is 17 months old too.
Alice28, after reading your description of how Molly nurses I give you so much credit for sticking with it this long. Madison was exactly like that in the beginning and it was so frustrating. It was worse for her at night though, when she'd get very tired andhungry, then she'd unlatch, scream, I'd try to get her back on but couldn't while she was crying. Ugh, it was a nightmare. That was another big reason for me using bottles so much in the beginning. By the time she was a month old, however, she worked her issues out (I say it like that cause I dont' think I helped her in anyway) and became a super nurser, but gosh was that hard until she did. If she had still been in that pattern at 5 months, well I don't think I even would have made it to 5 months.
Tasha, when Madison was 12 months she wore 6-12 months. My mom said the same thing when I would buy in advance, that the outfit would be too small, including things I bought when I was still pregnant. She went on and on about what size I wore at what age, and it didn't help that at 9 months my 4yo niece was the same size that my daughter is now. For Madison, at 12 months some outfits were 6-9 months and fit, others 9 months, and then some said 6-12 or 9-12. She was barely in regular 12 months and almost nothing that said 12-18 months. She was 19.7 lbs. and 29 inches, 25th percentile in weight and 75th in height, in case that is more useful to you. So the reason for her sizes was more about the weight-pants just fell off her waist. If she had been a bit heavier she would have definitely been in 12 and 12-18 months. She's 17 months now and a lot of the 12-18 month stuff is still big on her, and I don't see her going to 18-24 months for awhile. But again, like I said, if she weighed more she would have definitely been in her size, and since there's a 75% chance that Kylie weighs more, I'd go with the 18 months too.
DisKim, we had the same dilemma about when we started Madison on solids so here's what worked for us. We were going to be in DL when she turned 6 months, which was when we planned to start her. So I decided to start about 3 weeks before the trip, but she wasn't really interested in it yet either. It surprised me since she was over 5 months old and always showed interest in our food. So after about 2 weeks (I took a couple breaks in there and restarted) I gave up and decided to wait till after the trip. This worked out much better for me because then I didn't have to pack cereal/bowls/spoons and pump milk to mix the cereal with. When we got back she was 6 months and a week old and seemed much more interested in eating which made it much easier for me. It still took awhile before she'd eat much though, and even now she's not a big eater, which I'm pretty happy about, and eats a small bowl of Cheerios and milk, with a little barely cereal mixed in.
