Hi, DD is 5 months old and has been showing signs of being ready for solids for about a month. She's mesmerized by us eating, makes chewing motions, can sit up mostly unassisted. She has also doubled her birth weight (weighs around 18-19lbs) and it has been increasingly hard to get her to go the full 4 hours between feeds (she is exclusively BF). She started sleeping through the night at 7 weeks. That only lasted until she was about 13 weeks, since then she wakes up 1-2times a night to feed. We tried DD with rice cereal mixed with breastmilk for 4 days in a row. She would spit it out, push my hand away, turn her head, make sour faces. I don't know if she's just not ready or just doesn't like the taste??? What do you guys think?? TIA
