Hello everyone, Experienced moms, please give me some advice! I'm introducing solids, and have been happily eating porridge for a month now. But vegetable purees are a nightmare! They leak, they get fussy, and they just won't eat them. I've even bought pre-made ones and made them myself, but it's useless. It turns out that one feeding I replaced with porridge, but the second one is impossible to introduce. How do I do this?
