My daughter was EBF until 23 weeks, when I started weaning, but has been having a bottle of expressed breast milk pretty much every night from her dad since about 4 weeks old. She has never had formula, just breast milk, and we never had any problems with her taking the bottle.
In the last few days, she has suddenly started refusing the bottle. It coincided with us doing CC sleep training - the bottle feed is the one before she goes to sleep, topped up with a breast feed if she is still hungry. It started off with her only taking a couple of ounces, but still BFing, then sh refused to take it all together, just chewing on the eat. Have managed to get her to take a couple of ounces through the cup she gets water from but she really resists and it's clearly a distressing experience for her.
Is this most likely a side-effect of the sleep training, associating bottle with crying, or teething issues because the teat (Tommeee Tippee) is nice to chew on? I have tried offering her the bottle at different times of day but the same thing happens, I've also tried a faster flowing teat.
Any thoughts gratefully appreciated.
