The majority of fans were full of praise, but some followers were quick to criticise.
“It’s cute but also kinda weird,” one person wrote, while another described the image as “strange”.
Another added: “Some pictures should just be personal… love for your family but not out in the world.”
Others hit back at the negativity and heaped compliments on the Pretty Little Liars star and her brood.
“A beautiful mama and her girls at one with nature,” on follower gushed.
Another tweet read: “Gorgeous Tammin! Teaching your girls to be strong and confident! Oh my God I absolutely love this.”
Tammin shares her daughters with actor/director husband Sean McEwan, who she wed in 2011.
Her journey to motherhood has been made even more magical after suffering two back-to-back miscarriages before giving birth to Lennon.
She openly talks about those dark times in a bid to bring light to a very common problem that is often hidden away and not spoken about.
“Last week was the first time I've experienced loss. That's as much as I'm going to say right now but I do want to write about what we have been through at some point to help anyone who is also going through it,” she wrote in 2017.
“You become angry and you don't know at who to be angry. You realise that your anger just stems from pain. So if you are hurting this holiday season, for any reason, know I'm with you and I see you. And the only way out is through. Together we got this."
