Fidgety 3 month old while BF

Tanya

Is there anyone out there that has a super fidgety 3 month old while feeding. It’s kind of come out of no where...she’s constantly moving...sometimes “playing” with the nipple, then arching her back, kicking her feet?? Please tell me I’m not the only one and that this is a phase? She’s my 5th and I feel silly for saying I don’t remember any others doing this!!!
