my niece had tongue and lip ties. she just got them fixed after she turned 1. breastfeeding was a nightmare for my sister because she wasn't latching properly. Drs. didn't diagnose it till she was about 9mo
If your baby is struggling definitely see if you can get it clipped. My son out grew the issue, thankfully. But a tongue tie can lead to weight gain issues as you can see it's hard for them to eat.
