My 1 year old is constipated!!

Dee 💜 • Mommy to Kaylee 👶🏽🎀

My baby just turned 1 last month and she’s not on formula anymore but it’s like every milk we’ve tried she gets super constipated, what milk is sensitive enough to prevent constipation other than Can milk? Can I just put her back on can milk until I feel it’s time to switch it up? ( she was on simulacra advanced)
