My 12 week old ds has recently( in the last few weeks) started putting his hand in the way of his mouth whilst feeding as well as squeezing my boobs. It looks sweet but it sometimes interferes with the latch and I have to keep taking him off and putting him back on again. I wondered whether he liked the milk to go on his hands because he licks them after the feed!!( must be his idea of dessert) Or is it because he is just discovering his hands? The other thing is that even when his hand isn't in the mouth with the nipple, it's in the way so I can't see that he is latched on correctly. DH says it's the start of him being secretive from his mum!
