Baby poop question

Kelsey • TTC baby #2❤️ Baby girl born 03/26/2019🎀💗

LO is 4 months old, she’s had some baby food. Oatmeal yesterday & prunes today. She’s been straining like she needs to go and pushing but nothing would come out so I stimulated her anus with a qtip and it came out way thicker than usual. Besides baby food, she’s breastfed with the occasional bottle of formula.
